-Hello- Amy said after lightly knocking on the open door of Sheldon's office.

-Hello- Sheldon answered looking at her somewhat surprised since he did not expect to see her- Have you finished your project?

-What ... -she was about to ask Sheldon what project he was talking about when she remembered the little white lie she had said that morning to avoid coming with him to work- Oh yes, I'm done. Thanks for asking.

-I'm glad-added-Do you need anything?

-I came to tell you that I'm going home, in case you wanted to go with me. Or if you prefer to go with Leonard ...

-No, I'm going with you- he began to collect his things from the desk -Then, tell me about this project of yours.

-It's not something you want to know-she shrugged- I'm sure you'll find it boring.

-Amy, you're my friend. You can share this kind of things with me, even if I think they are boring-he turned around to see that Amy had stood in the middle of the hallway- Are you okay?

-I ... -Amy wanted to say and ask many things to Sheldon at that time, but all she said was ... -Who are you and what did you do with Sheldon Cooper?

-Amy, are you sure you're okay? - He walked to where she was and put his hand on her forehead to check her temperature.

-Yes, I am fine. It's just that ... in these last days you've been acting weird.

-According to our friends, I've always been weird, so I don't know why you're so surprised- He frown. They almost always agreed, but sometimes like this, he did not understand her.

-I mean that ... wanting to help me with my work, or listening to me talk about it, are not things that you liked in the past.

-You're right. But I was serious when I said I wanted to be a best friend for you… -He bit his lip- And for the others.

-Oh ... -Amy was silent for a few seconds without taking her eyes off him, what made him feel a little awkward and he wish he had a machine to know what she was thinking- I'm glad-Sheldon nodded and continued walking towards Amy's car.

-I just remembered, today I won't be able to watch Supergirl with you-Amy said after they got into her car.

-It's okay.

-Are you not upset that I canceled our plans?

-No.

-That's really surprising.

-The truth is that I forgot that we would watch Supergirl today and had already made other plans.

- Will the boys and you go somewhere?

-My plans don't involve them.

-So with...? -Amy looked at him sideways for a second- Do you have a date with Vanessa?

-Yes, does it bother you? - Sheldon asked.

-What? No! Of course not!

-Are you sure?- She nodded.-Because you used the tone of voice when something bothers you.

-Yes, well ... I'm surprised that you have a date with her, that's all- Sheldon looked at her for a few seconds as if assessing if what she had said was true or not -And where will you two go?

-She will go to the apartment.

-What? -She asked more surprised than she would have liked- Don't ... don't you think you're going too fast?

- Go too fast? I am not the one who's driving.

-That's not what I mean.

-Well, explain to me Amy, because I am not understanding anything.

-Invite someone to your apartment on the first date, it's like saying you want to have sex with her.

-Oh ... -he opened his eyes- Oh ...

- Isn't that what you are planning?

-Are you listening to yourself, woman? Of course not! -Sheldon looked at her confused- You know me well. Why do you think I would have coitus with a stranger?

-I don't know- she shrugged-Maybe it's because you've changed your mind about a lot of...

-Well, my opinion about coitus hasn't changed- he interrupt her. And Amy didn't know if she was glad or angry about that- She'll just go to see my comic collection.

A couple of hours later Amy appeared in the living room and observed Sheldon who was sitting on the couch playing with his cell phone.

-Won't you dress for your date?- she ask curiously to see that he had a superhero shirt on.

- Now you have vision problems? I'm already dressed

-I meant ... -She rolled her eyes-Forget it.

-You mean why I'm not using something more elegant- Sheldon asked and she nodded- I already told you that Vanessa will only come to see my comics. What I am using is perfect.

-Yes, you're right.

-And for the clothes you are wearing I will assume that you have a date with your boyfriend -he said before making a face.

-Yeah- they looked at each other for a couple of seconds- Have fun on your date.

-You too.

Amy had just opened the building door when she saw Dave's car parking in front of her.

-Hello-greeting her giving him a quick kiss on the cheek.

-Hello Amy-Dave wait for her to put on her seat belt- Are you ready to go? -She looked at the window of her apartment and then at Dave.

-Yes I'm ready.

They arrived at the restaurant and a waiter took them to their table, Dave arranged the chair for her to sit down and Amy thanked her with a smile. The waiter took their order and then withdrew while they continued talking animatedly about her work and his.

Dave was telling her about his math job, when Amy yawned.

-I'm sorry, I know it's boring to talk about math...

-No, no no-said Amy- None of that. It's just that I woke up earlier today than usual and I'm a little tired.

-Oh, I understand- Dave sighed with relief that Amy didn't think he was boring-Why you don't finish your dessert while I ask for the bill and then I take you to your apartment.

-It doesn't bother you? It's still early-she said, checking the time on her watch.

-It's okay. You must rest- She nodded gratefully and continued to eat dessert.

When they returned to Amy's building, Dave opened the car door and helped her out. She was about to say goodbye to him, when she heard a voice behind them.

-Amy! - She turned to see Penny who had been walking hand in hand with Leonard- Hello- said the blonde looking at Dave.

-Hello- said him.

-Aren't you going to introduce me to your boyfriend?- Amy blushed. While they have been going out and even kissed a couple of times, but they had not talked about the state of their relationship.

-Yes ... mmm ... he is Dave-she look at her friends- and they are Penny and her husband Leonard Hofstadter.

-Oh, my God. Leonard Hofstadter! -he exclaimed excited- I knew I know you.

-Do you know him?- Penny asked, looking surprised at her husband.

-I…

- I met him at a conference a long time ago. Obviously someone like him wouldn't remember me, but ... I'm very excited to see him again.

-Anyone like him?-Penny whispered to Amy who looked equally surprised. "Do you know what's going on here?

-No idea.

-Dr. Hofstadter is like a rock star- Dave said, still smiling-What are you doing here Dr. Hofstadter?

-Call me Leonard-Dave smiled even more- And I live in this building.

-Really?- Leonard nodded-I remember you commenting in the conference that you was living with Dr. Cooper and working together." Penny and Amy looked at each other.

-Well, that's how it was. But I got married and ...

-Of course-he look briefly at Penny-I imagine that now you only sees Dr. Cooper at work.

-In fact, he lives in the apartment in front of mine.

- Did you hear that Amy? Dr. Cooper lives here - he look excitedly towards the building.

-Yes, I know- she said somewhat uncomfortably.

- Do you think it would be very strange if I go to his apartment and told him how much I admire him?

-Well, he enjoys it when someone praise him-said Penny.

-Excellent! I know you're tired, but you would mind joining me to see Dr. Cooper?

-I don't think it's a good idea.

-Why not? Just a few minutes.

-Well ... Sheldon is my ex-boyfriend-Amy admitted, waiting to see Dave's reaction.

Oh ... that would be awkward, right? - Amy nodded- Well...-he thought for a few seconds- It doesn't matter. Could you introduce me to him?-he ask, smiling again.

-Do you think it's a good idea?- Amy looked surprised while he nodded. -I ... let me think about it. Maybe in a few days I will present him to you. As I told you ... I'm very tired.

-Yes, you're right- he kissed her cheek and shook hands with Penny and then Leonard- It was a pleasure to see you Dr. Hofstadter

-I didn't think it was possible, but it's even weirder than Sheldon-Penny commented as they were in the stairs.

-My kind of boyfriend seems quite in love with my ex. What I am going to do?

-What can you do with two men? - Penny looked at her amused- Have you learned nothing from what I taught you? I'm sure Dave would love the idea-she raised her eyebrows suggestively

-As if Sheldon were to accept something like that. He didn't even want to do it with me.

-Maybe that has changed.

-What are you talking about?

-Don't listen to her- Leonard said- She have a couple of drinks and don't know what she says.

-Leonard.

-Penny- her husband frowned.

-What is going on between you? - Amy asked.

-Nothing. Have a good night - he took Penny's hand and almost drag her to their apartment.

Amy moved her head. It had been a very strange day, she thought as she opened the door without knowing what she would see on the other side.

Hey! I'm going to go out of town for a few days so I wanted to update before I go and wish you a Merry Christmas to everyone! Thank you all for reading and commenting.
