I am flashing back to the time when I was younger. I remember how I would ask for favors but never got them. When people reject me like that and expect me to help them the next time, i try to be the bigger person and help them. After that, they still consider you nonexistent and that you're only there when they need help and then they make all kinds of promises that they can't kept. Why should I even try? Go ask somebody else for help. I am not a thing that you can only rely on when you need help.
