Has anyone else noticed this too?
I have notice this. Also, I've seen several ENFJs do this. They smile this huge smile where their teeth are totally clenched together. It looks like this ---> (but of course, there aren't teeth on that smiley, so that doesn't really help). It can look like a fake smile, but they're really smiling.

Maybe some types are more uptight? and that's why their teeth are clenched together like that? Where as as an ENFP my teeth would be more apart when I'd laugh.

FDG, it doesn't look weird when they do it, it's just a different way of smiling. (I just smiled at you with my teeth clenched)
