I probably won't be angry by the time you read this. When we're not posting two or three hours past our self-imposed deadline, we actually do aim to write these things in advance. That's how it is for me now: I'm writing this post in advance, and I'm angry.
There's nothing in particular that triggered it. I got up, went to work, came home, watched a movie with my wife, and started prepping for the weekend. Fine and dandy. But I've been angry all day. Lack of sleep? Anger-inducing dream I don't remember? Stressed about another weekend booked solid from Friday until late Sunday, no matter how fun the activities consuming it might be? I can't say. I'm just angry at everything.
To the casual observer, you might not be able to tell. I've still smiled and laughed and generally been myself. Yet my default position all day has been simmering anger--if that's even a position--and the little things have been much quicker to get under my skin, and good things need to be way better than average to feel all that good to me.
Bruce Banner says in The Avengers that his secret to keeping The Hulk under wraps is that he's always angry. I understand exactly how that feels today. And I really don't know why.
