Since your college years, have you ever (other than in a moment of blind anger) told someone you hated them?

No, never reveal your cards to anyone. Keep your enemies close and fuck them over.

"Save your hate for wars."

--my grandma when i was little and said i hated someone or something

No, but I do see red and I have to suppress the compulsion to swear a blue streak.

I told my step father I hated him, when he was on his death bed suffering. It was fantastic. It wasn't in anger, but more a factual, calm conversation. I said, "Now that you supposedly only have a few months left, I want to be sure you know how much I've truly always hated you. To see you suffer like this makes me want to celebrate. When I leave here, with you in this state, I'm going shopping." I was giddy. I never spoke with him again, and just thinking about it puts a smile on my face.

R4. That's intense, but sounds like good closure.

Nope. I get angry and hate shit people do, but even if I’ve immensely disliked someone, I’ve never told someone I’ve hated them.

Every fucking night.

To their face? No.
