I will run away.
I will not talk to you.
I will look away.
I will look at the floor.
I will mumble terrible replies to anything you say.
I will stand there twisting and turning with my friends in the same spot make groaning noises trying to muster up nonexistent courage to talk to you even though I’ll never muster it up.
Basically, I will act like I hate you, and you will think I don’t have any interest in you, but I do. I so do.
