When kids would mess with me in high school, sometimes they would try to disguise their intentions. I got pretty good at figuring out who was being genuine and who wasn’t.
I’m going to suggest the unthinkable and say you might think about actually punching one of them, right in the face. You’re going to want to make sure he really has it coming. And you want it to be as visible as possible, you want the whole school to know about it.
Then the next time someone asks you out, you can say something like, “sure, but the price of a date is that I get to punch you in the face.”
