Yep, I don;t “hate” anyone, strongly dislike maybe, but hate is a waste of energy, the true opposite of love is not hate, it is, as @MollyMcGuire said, indifference. Don’t hate your enemies, just ignore them.
Introspection. (That applies to me. When I find myself hating someone I look for the flaw inside myself. I don’t always find it – and even when I do I don’t always manage to fix it – but I know that it’s there.)
I’ve had a few bosses I’ve hated and their names were Susan and Sam so my answer would probably be Susan and Sam. Other than that, I haven’t hated many people. Dislike, yes.
