I am definatly someone that this happens to, I do it because I am afriad of not being wanted or someone using something against me to get others to not like me. I have been pressured into a lot of things recently..
I am not the type of person that can be peer pressured simply because I am a mean individual. If I ever did something that was wrong it was because I honestly wanted to but we won't get into that. BUT I can get peer pressured in thinking things such as running away.
