This is my little brother. Needless to say, he's got "angry" down. Note his proximity to both beer and attractive women. Nevermind the fact that he's at a cheesy sports bar and that the women are practically his sisters -- there's beer and there's chicks, and therefore there's no excuse for that grumpy face. And the middle finger. . .my god!
The thing is, angry is my brother's natural state. Being pissed about everything is like his version of happy. If he's not scowling and giving you the finger and calling someone a douchebag, something's not quite right in his world.
I have a secret though: he's not really that angry. He just pretends. Oh sure, he's fired up about Darfur and religious fanaticism and the erosion of our constitutional rights and all that, but he's not one of those people you hate to be around because they're so negative and they never stop bitching. He's more like a funny guy whose bitching makes you laugh. Sometimes even he has a hard time not laughing at his own angry act.
Occasionally though, he walks a pretty fine line. Referring to him as "Dad" is usually enough to make him snap out of it in a hurry, which is good because really my brother is this guy -- the happy one with a smile on his face and his middle finger being used only to grasp a can of Bud.
I like funny angry little bro' an awful lot, but it's funny happy little bro' I really love.
