I'm going to prom with another girl
So what reason do you have for going to prom with another girl?
Yeah, the first girl rejected me.
It is good to make different plans if the first ones do not work out. You should still be able to enjoy your time if you get rejected.
It doesn't matter, nothing will go well if that bitch wont go with me. I hate her.
You shouldn't be so mad that someone rejected you, as you've already found another girl willing to go out with you. You need to realize that you've found someone better for you already and be happy with them instead of obsessing over someone who clearly wasn't interested in you.
