At times good is bad with bad, so you will do good and be paid with bad. There are people who are not mean around you. Concentrate on those who value you, and love you. You will never be liked by everyone you treat well and do not mind those who are mean to you.
Well if you really want to get back at them, pray they suffer the same mental ailments that I've been going through. I was real pr-ck to a lot of people when I was younger, and I believe I'm still paying for it. Of course not being too high on the social pecking order myself, I received my own share of psychological/physical torment which I in turn passed on down to those below me in the "food chain"
Bc/ they wish they wer more like you.. and bc/ their that's the only way they know how to make themself feel better is by trying to make you feel like crap. and others.. and people also sometimes are mean to others who are different or not like them.. / you never know what happens at home behind closed doors.. sometimes kids who behave this way have a lot of Family problems , they wer never taught to be nice..
