How dare you break my friends heart?

Thanks to this bitch my friend had a bad day. My friend is bi and liked a guy. So he sent him a carnation anonymously. However the teacher was a curious asshole ad compared his and writing on the note and said it was my friend who sent the guy the carnation. The guy was so rude ripped the carnation in half and threw it in the the garbage. Dude I know youre no bi but it does not give you the right to ripped my friends heart. People have feeling and you need to be considerate of those feelings. That just pisses me off.
