Have you seen the studies showing that depressed or otherwise irascible folks actually have a more realistic view of life ?
The rest don't much like having illusions whacked at.
FWIW, I get pissed at you occasionally but I don't hold a grudge, and I kind of expect that you'll get pissed off at me as well - it's got to do with being human.
It's the folks who hang on to it like it's a pet that worry *me*.
