agro over nothing.
Yeah - I call that "having a bad day"... when you're in the middle of one, sometimes you explode for no obvious reason (to other people).
And then there's the bipolar people. Just because they're crazy, doesn't mean they don't have a useful contribution to make - if only to toughen the rest of us up on the "exciting" days. Mind you, I'm really really careful around these people in face to face contact, their anger is not something that makes any sense to me and is about as comfortable as being in the middle of a thunderstorm.
Does that mean I have to actually read the snow dogs thread. Sigh.
