It could be body language. I think people don't like me because I have trouble smiling and am not eloquent. When I meet someone new for the first time, that person is very warm and welcoming to me. But during the second and third times, they're not as friendly anymore and sometimes they avoid looking at me or even go out of their ways to avoid me. This is why I don't do well in classroom situations. The longer the class, the worse it gets. People form deeper impressions about me, most often negative.
That's how it was at my old school. At first people don't know me so they're indifferent to me. But once they found out who I was, thanks to a bunch of gossips and rumors, it became hell. Almost everywhere I go, I hear people pointing me out and saying “isn't that the stupid girl?” “that's the girl that everybody hates...” And there would be awkward silences while I walk with my head down, ashamed of being who I am.
On the other hand, I do better in one-time situations such as shopping at the grocery store or going to the airport. I go to these places very infrequently. Cashiers and customer service reps probably don't remember me at all and therefore, won't have time to form any impressions about me. I could pretend to be extroverted and they wouldn't have a clue. If I mess up, I don't have to go back there again. It's all short-term and will be forgotten.
