When confronted with that situation I appeared to to "help", but they were usually left with a "what the ###$ " feeling. Ya,
want to give those type's a "what the ###$" feeling, like we don't apply to each other. Go back to your circle, and play with your kind. The magnanimous approach works best I think. Revenge is to repeat what they initiated, letting them draw you into their cycle.
Are you good in school ? Are you developing any special skill's ?
I have trouble relating to some of your post's because we have few area's like that in the USA. Yes, we still have old working class neighborhood's, but people tend to live there by choice, and they are fewer each day. People who don't want to live there get degrees, or skills, and move. I hope that is an option for you someday.
