3 of them for me.

I use the first one most of the time; the one that seems silent & that usually makes me seem unfriendly, which also creates misunderstandings now & then, mostly while I'm on the internet. It's not like that in real life though. I'm neither as cold, nor as silent as i seem to be, but whatever. I'd consider it to be kind of a "neutral" face.

About the other two, they reflect by bad side, which is deeper than my not-bad one. The first one is my usual "Wrong" face, the one that i use when i'm not feeling good, or when i'm a bit pissed off etc.. Makes people around me feel uneasy, guilty, kinda bad. It took time to master it.

The last one is something very few people have seen & doesn't come out unless the situation is very, very bad. The good thing is that no one from the forums will probably ever see that, so it's all fine.
