Bad people are bad, as it happens.

The one mutual friend I have with Shitlord's other guy was all "at least he finally came to his sense".

Shitlord's sudden forceful overtures of friendship are just because he got dumped.  After months of ignoring me he wants to be friends because he has lost everyone who likes him and needs someone to feed his narcissism.

How did I forgot how much he uses people enough to think it was worth investigating the possibility of friendship.
