I will say this one more time, and one time only. Then I never, ever want to repeat it. He trolled me for weeks over the death of a friend of mine. I found that to be inappropriate and unacceptable. He refused to stop, so I stopped speaking to him. He could have very easily apologized, but he refused. He refused. He thought he was within his rights to rail me mercilessly, saying horrible things about my dead friend. So he is 100% persona non grata in my world.
In other words, FUCK HIM. Fuck him with a long, sharp, burning hot poker. Fuck him all the way through to his tiny brain.
