You

My coworker is wondering why I'm sitting outside in the cold instead of
inside our heated shed. Should I tell him?
"It's because I think you're an obnoxious sloppy idiot, and I don't like
spending time with you. I don't want to listen to your completely inane
chatter. I'd rather sit in the cold. Thanks. And throw away your stupid
smelly food when you're done with it, outside the shack.

Don't leave it in here for me to clean up in the morning."
Man, why am I in such a bad mood? Maybe it's the no food or sleep thing.
And the cold. And manual labor. That can't help. Plus, I think he really
is an idiot.
