One screw too tight

Okay, I admit it, it's true. I get just a little up tight sometimes. Someone read my blog and later told me that now they know what's wrong with me.

"It's not that you have one screw loose, it's just that one of your screws is too tight!"

Yeah, thanks for the psychoanalysis, dude, it's just what the doctor ordered.

Unfortunately, and this is the scary thing, my wife agrees.
