Floridaman, I think it's what you pointed out.
If you feel inferior, all you body and your face are going to express it.
So, people as an innate ability are going to catch it up.

Many psychogical problems have in common the low self-steem. It takes work to get a better self-steem but you all can get it. The help of therapy is very useful to change these thought patters and working in social skills as well.
