You get kind of scared and say with your now boy voice:
- I changed my mind lets switch back.
But he now in your older and more agile body just pushes you away and says: "I don't think so, balloon boy!". You realize you're starting to lose your adult memories, instead you're learning of the little boy's memories, you vaguely remember that your girlfriend was going to meet you at that spot, you suddenly get worried that you're going to lose your girlfriend.
"Please let me have my body back, I'm supposed to miss my...uh..girlfriend here and I don't want her to see me like a little kid."
"Tough deal balloon boy! I guess I have to take care of her from now on!"
He then sees your girlfriend approaching from afar. Since he now has your full memory he waves at her, and she sees it. With a big smile on her face she approaches him, gives her a hug, and with a quick kiss on the lips, she turns toward you and asks him:
"Who's the balloon boy?"
You try to tell her what's going on, but you can't remember her name because now you have the little boy's memory, so helplessly in your childish voice you tell her:
"No! He switched places with me. I'm your real boyfriend."
She didn't believe a word of what you say, but tries to play with you a little bit:
"OK, so what's my name?"
You can't remember her name, and your childish character is starting to take over so you start crying:
"I don't want to stay like this!"
So she takes his hand and says: "Sorry cutie, but we have to leave. Have fun little balloon boy!" with that they walk away. You try to go after them, but suddenly a security guard says:
"Hey little kid! are you lost? Were are your parents?"
You tell him the story, and he just laughs it off, and says: "come on I'll take you to the information booth and page your mommy and daddy!"
So you go to the information booth and...
