There are other things I can't bring myself to do in game. I can't run Sunken Temple. Every time I go in there it's like my brain forces me to come up with a reason to leave. And I'm beyond terrible at playing a paladin - every time I try I end up getting myself stuck at some random level, and often, I end up deleting the character. I recently started playing a paladin I'd left at level 50 since vanilla - he's since been deleted. I have friends who simply cannot play Horde, or Alliance.
So, let's ask the question - what can't you make yourself do anymore? What couldn't you ever do?
