Hall of Infinite Doors

You've gone on the trip so many times it's seared in your brain. As you step over the gate to the bright red elementary school, you scan the grounds for any sign of Piper. You spot her sitting on a bench eating a sandwhich.
Piper has long curly brown hair tied up in a ponytail, intelligent blue eyes, tanned skin and a small nose. You've been friends ever since you accidentally kicked a soccer ball onto her face. She is the smartest kid you've ever met.
"Hi, Piper!" you call out.
Piper looks over and smiles. "Hi Micky!"
What do you do now?
