What does this indicate?

In middle school and high school I would get made fun of because I didn't have as much shoes as the others. Well one day when I finally came to school with new expensive shoes they started calling then spiderman shoes because they were black and red. Another time I got shoes they were black and they some people started making fun of them because they were "big". Everyday they would come in and look at me for something to pick at. No matter what they have something to say. I wore shorts once and one guy laughed at pointed at that. These were mostly guys who did this but girls aswell because they were all friends. One time they even made fun of my white socks. Its really weird how closely and often they would look at me. Recently I saw one of the girls who made fun of me at college and she looked at me like she didnt want to see me there.
