1) The Last Post Wins: The thread that made me stay. (I don't mean like, to win the last post, I mean the people who're usually active there). I also have a special fondness for The Nightwatcher thread.
I'm in PM groups who never fail to cheer me up either!
2) the memes, of course. Some funny AMA responses too and almost every other Forum Games thread. Special mention to the goat thread.
3) I was being tag-teamed, someone I had previously argued against was the first to defend me (and they didn't think much of it either). I've gotten dog-piled multiple times, it's always nice to have someone come to your defence (special thanks to you three, you know who you are and if you don't there's PMs waiting for you!)
4) Old theory mega post by Argent about the whole situation on Roshar. Literally whole situation. And it still holds up. True Art.
5) I've said politically contentious stuff. Looking back, I'm proud of every stance I've taken, and the ones I wasn't proud of I've already apologized for. (if this makes you pause and want to say something, please DM me rather than derailing this thread)
6) I'm more of moving forward kind of person. If I had a time machine I'd redo/re-experience far more than just my time here (not trivializing my time here, but people who are physically there will always come first!)
