That this is the only place I can bitch about my job and be understood

Yep. I love my wife but if I started talking about race conditions and null pointers she'd stare at me with a blank look on her face. And for some reason problems that I spend all day on doesn't sound so terrible when trying to explain it to a non techy. "You see, this 1 is supposed to be a 2.. and I spent all day trying to figure out why it isn't."
