In the first place, money should never be in the equation when it comes to friends. I remember i got a so called friend once that always ask me to invest in forex telling me how much of $$$ he can generate for me per month. I say straight in his face. If u believe in ur money making ability so much, get ur own parents to mortgage their house and use that sum of money to generate more money for them. Thereafter i never hear from him again. Good riddance to bad GARBAGE.
If making friends is about getting some benefits from them best to just get lost. Coz the main purpose of friends is to offer emotional support not monetary support.
