Turn him into a woman.

 You quickly write on the notebook “i wish John was a woman”. You see him change in a matter of seconds, and his upset look quickly change to a simple smile. 

“Amy, what are you doing here? I really have to pee” she says. “You are the one who asked me to join you in here” you say while giggling. You step out of the plane’s bathroom and go back to your seat.

You can’t believe it worked. What you wrote in that notebook became real. While your friend was in the bathroom, you start reading previous wishes, you realize that a few wishes back, you used to be John. “What the hell? But I am Amy! I remember being me my whole life” you whisper. “Maybe i used to be him, but it’ll be weird turning into a guy.” You tell yourself. 

Your friend joins you, “what are you reading?” She asks. You hide the pen you were holding, and hand her the notebook. “Read this” you say. She takes a while, “these are wishes? You used to be John, but i also used to be John? And now we are both girls?” She asks. “Well i am you, and you are a new girl” you say, explaining that she is the original Amy.

“We could have anything and everything” she says. You agree, “but I think we should first do things right”.

You take out your pen, grab the notebook, and write:

• While keeping our current memories, we swap bodies
• We go back to being our original selves
• Something wild
