I'm going to reject a guy in front of the whole school and tell him ''you stink''.
Why would you do that in front of the whole school?
Because I may be a heartless bastard.
Thats a really cruel and crushing thing to do to someone in public. You should do it private and not in front of the whole school.
I don't care if it hurts him. He would do the same to me.
Have you considered how you might look to other people if you do this? You could look like a bully and then people might want to avoid you if it backfires.
