I smile when i really shouldn't
It's been like this for a few years now maybe. When talking to people I tend to smile when I'm annoyed or angry. It gets really weird when I'm flaming with rage inside when talking to someone, but can't get the smile off of my face. It gets weird when watching movies too. During sad moments, when others would cry or often even at the sickest horror scenes I find myself smiling (Maybe that's because of the awesomeness of the scenes? Yet no one I know seems to react like this). It would be really weird watching movies with someone, I probably look like a serial killer when watching horror films. I'm not sadistic or anything and I'm pretty much the most peaceful guy you could find around where I live. I know it's not a major problem but is it normal? Does this keep happening to any of you?
