I avoid social things because they seem way too intimidating for me and my selective mutism kicks into gear so I can't talk anyway. I avoid going down on escalators (I can handle up all right) because I have an irrational fear of accidentally stepping between the stairs and falling all the way down once they open. In general I don't avoid other things, because I get called lazy or accused of not caring if I do. Of course, I get the same thing if I try and fail, even when I was trying my hardest, but at least then I know that I really tried.

Yet in my new wildness and freedom I almost welcome the bitterness of alienage. For although nepenthe has calmed me, I know always that I am an outsider; a stranger in this century and among those who are still men.
