Wandering's for sure, it was almost beautiful. I may have been a catalyst to his self-death, but he has assured me that I wasn't the reason he left. Which made me feel warm inside.
Rat's was basically a giant dummy spit over a non-subject. It's about time if you ask me, he's been banned 3 times or something and always came crawling back. Hopefully the mods will have the good sense to not let him back.
