Author's Note: Great news! Even though this started as a school assignment, I decided to continue this story!

Just to answer chibi-chan 2013's question: I don't want come out and say what age I think they are. As you'll see when you read, this chapter has a flashback. Phineas and Ferb are graduating early, so the whole gang is about seventeen in the flashback. Chapter 3 will reveal how much time has passed between the flashback and when Isabella "broke into" Phineas's house. I'll just let people do the math from there.

Disclaimer: I don't own Phineas & Ferb. Or do I? Nope. Disney does.

"Isabella?" I asked again, still in shock.

"Yes, I'm Isabella, and you're Phineas," she answered a little more sarcastically, "So Phineas, whatcha doin'?"

"No, I know you're you, it's just- wait a minute! What do you mean, 'what am I doing?' I'm not the one who broke into my house! I mean… I suppose I'd have to break into someone else's hous… umm… uhh," I started to stumble over my words as my brain tried to process this situation.

"You're not good with being woken up in the middle of the night, are you?" she teased.

I let out a sigh, "No, no I'm not."

She chuckled a little, "Oh well. Besides, I didn't break in. See? Your windows and doors are still in one piece."

I noticed she was right, so I asked, "Did you pick the lock?"

"No"

"Did you crawl in through the platypus door?"

"No. Why on Earth would I do that?"

"Did you crawl down the chimney?"

"You don't have a chimney, Phineas."

I decided I would be easier just to ask: "Well then, how did you get into my house?"

"I teleported here," she said like the answer was obvious.

I gave her a blank stare. "That's interesting… but where would you get a teleport? Last I checked, only Ferb and I knew how to build that kind of stuff. I didn't build you one, which leaves Ferb. Now why would he-"

"Actually Phineas," she interrupted, "You did build this teleport. Remember these?" She picked two ceramic turtle doves up off of the table. I hadn't noticed them up to this point, but as soon as she showed them to me, I remembered.

I slapped my forehead with sudden realization, "Oh, I remember that day."

Flashback (Phineas's POV)

It was an early morning in July. Ferb and I, as we had done since we were ten, were sitting under the tree in our back yard. Isabella, Baljeet, and Buford had joined us that morning to decide what to do. "So Ferb, what do you want to do today?" I asked, "I mean… we can't not do something. This is our last summer before college, and we need to make sure every day is the best day ever!"

Isabella sighed, "I still wish you guys hadn't chosen to graduate a whole year earlier than the rest of us. Not only that, but you'll start college as sophomores!"

"I ain't happy about it either." Buford added, "Not that I'll miss ya or anything, but I always thought being friends with high school grads would mean having an awesome grad party."

I looked towards him, "If you hadn't noticed, Mom and Dad threw a great party for Ferb and I the day after we graduated."

Baljeet piped up. "No offense to your parents, but even I thought that party was lame."

Isabella elbowed him in the side and gave him a glare. Then she sweetly said, "I think what Baljeet is trying to say is that as much as we all enjoyed your parents' party, we'd like it if you guys had another party. Y'know, one with a little 'Phineas and Ferb pizzazz'."

Ferb and I looked at each other excitedly. Yep, we were thinking the exact same thing. "Ferb, I know what we're going to do today. We're going to throw the greatest grad party ever!" Everyone cheered. "Let's see, we're going to need some invitations, a cake, a disco ball, an atomic chocolate fountain, and a building in which to put it all."

"What can we do to help?" asked Isabella.

I thought for a while, "Hmm, I know! Isabella, you and the Fireside Girls are in charge food. Baljeet and Buford, you two can make invitations. Ferb and I will take care of the rest. Everyone meet at the park by five o'clock." Isabella, Baljeet, and Buford ran off to get ready for the party. "Alright Ferb, what kind of building should we make?" I looked around quickly, "Hey, where's Perry?"

Author's Note: Please review. I just started a 5 day weekend, so I should be able to spend some time on this story and update it within the next two days.
