In most cases, around people who appear to be judgemental.
Especially in academic settings in my college. I'm terrified of
sounding stupid, therefore, I'm completely silent, but I also
fear that it might make me appear that way anyway, as though
I had nothing important to say. But lets see... those situations
and interacting with people I want to make a good impression to.
I personally experience a problem in a situation where Im vulnerable to being judged basically all the time because people are everywhere! I hate walking on the streets...
I second that! Or if I'm speaking to anyone who is in a position of authority. Then I think about it and feel like an idiot. I shouldn't feel intimidated by any human being.
