Quite often, I don't show emotion in situations that may warrant it. This, I believe, gives people the idea that I don't care about what's going on.
Well, sometimes I don't, but that's not always the case. Expressing myself at any time just doesn't come naturally enough to me. Perhaps this goes back to when I was a kid, when I got negative feedback from people for such a thing. I was convinced that showing how I felt was a source for criticism. I didn't want to give anybody a reason to say something insulting to me. Thinking this way, it turned into my being looked at as apathetic. I get confused about what the right outward expression should be.
I learned in an Ancient Civilizations class I took that Egyptians once considered emotion expression as a sign of weakness. Sometimes I think I would have fit in with their society!
