Stand up

I have noticed that alot of the time I never stand up for myself. I let people push me around, but I never really say anything about it. I don't know how many times I hear negitive things said about me in a day. I don't know what I do to have these things said about me I guess some people just don't know how to chill. I do my best to get along with everyone, and you probably thinking that every person has to go through this. But really do we have to? I mean I consider the word 'hate' to be a very strong word when you use it against someone. I have atleast heard it about me ten times a week. I just kind of laugh and walk away preteding it doesn't bother me but when I think about it it does. When your in highschool alot of thiings can go wrong, people judge, hate, gossip, and just be plain mean. So does that mean the person being bullied has to take it? I never thought so, but I don't do anything about it?? Why?
