I slept almost all day yesterday. I stayed up from Sunday afternoon to Tuesday morning. I learned last night that I shouldn't have done that. It felt really awful. I think some of me had fun, but I don't remember them after about Monday 1 p.m.
I have a job interview in two hours. I can't figure out if I should just stop now and get coffee and wait and be early and stuff. Am I a brown-nose? It's not something I've ever considered, really.
My mind often seems to go blank when I am writing here, maybe because I am uncertain of my audience. I'll try again in a little while, maybe after the interview.
