A sequel to my 2018 story "The Recluse of 4B and the Waitresses". Part 4 starts the day after the wedding.

The day after the wedding Sheldon was busy doing Physics in his apartment when he was interrupted by a knock on the door.

"Oh it's you Sally, I wasn't expecting anyone to disturb me this morning, Leonard and Penny know not to disturb me on Sunday mornings."

"Good morning to you Dr. Cooper, I didn't get you out of bed when I knocked on the door?"

"No, I was busy doing some Physics, I need to catch up, all this wedding stuff has cut down on my work this week. Anyway, where are my manners, please come in Dr. Garcia, would you like a hot beverage?"

"Actually I have come to take you out to lunch as a thank you for inviting me to be your guest at the wedding. After breaking up with Simon I was not feeling good but getting involved in the wedding cheered me up no end."

"So where do you want to eat?..."

Next day it was time for another Monday Physics discussion

"Hello Sally, did you enjoy the wedding?"

"Yes I did Leonard, how are the newlyweds?"

"Penny got a message from Bernadette last night, they arrived in Hawaii yesterday for their honeymoon, they get back in 13 days time. Penny says thanks to you and Sheldon for all your help with the wedding and she hopes that you can both come for pizza on Thursday."

"Thank you Leonard, I look forward to it."

Then Sheldon spoke "OK Doctors, before we got so busy with wedding stuff last week we were working on a draft paper together. I discussed this paper with Dr. Garcia yesterday and I have revised it, what do you think of the changes Dr. Hofstadter?"

Thursday night

Knock, knock, knock "Penny and Leonard"

knock, knock, knock "Penny and Leonard"

knock, knock, knock "Penny and Leonard"

Penny opened the door of 4A

"Welcome Sheldon and Sally" and then she gave them both a friendly hug.

Leonard said "glad you could make it Sally, have some pizza."

Sally said "Thank you Penny."

"Last Thursday we were so busy talking about the wedding I didn't get to know you properly Sally, where is home?"

"I'm from Florida."

"Nebraska"

"My parents used to work at 'Walt Disney World' but about 15 years ago they got transferred to 'Disneyland' so I moved to California with them. I went to college at University of California Irvine and then did my PhD and first postdoc at UCLA, a few months ago I moved to Caltech and got to work with Dr. Cooper and Dr. Hofstadter."

"Do you miss Florida?"

"Yes but California is my home now. How did you get to know Sheldon?"

"About a year ago Bernadette and I moved in across the hall from Sheldon. He was quite a recluse back then, we first got to know him when he got locked out of 4B. Leonard knew him from Caltech."

Sheldon then said "after getting to know my neighbours and their boyfriends they gradually brought me out into the world."

Leonard said "Sheldon would then come to Caltech to discuss Physics with me."

Sally "now I get to discuss Physics with the great Dr. Cooper, all thanks to you."
