I hate people who never stop smiling?!
I don't mind REAL smiles, or smiling for a camera or saying hello. I'm talking specifically about those creepy bastards who have a permanent smile glued on their face, even when they're talking, and even when they claim to be upset.
These people are annoying at best. Often they give me the goddam chills. Either way I have to avoid eye contact with them because otherwise I have a very strong urge to punch them or swing a blunt object into their mouth, or scream "KNOCK IT OFF WITH THE RAPE FACE YOU WEIRD BASTARD!"
The WORST is the ones whose smiling mouth also never closes. They say something and then just let their mouth hang open there, in a slack smile.
Does this kind of thing piss off or creep out anyone else?
