if your cousin stop talking to you just because you didnt lend tem money wat would you do..!?!??!!?
If your cousin stops speaking to you because you wouldn't lend them money, then you need to sit that cousin of yours down and explain your reasons. Just because you have some money, doesn't mean it's "extra" or not needed!
I would ask my cousin what his/her problem is. Not everyone has money to lend out. Explain you can't do it, and that you are sorry, but they need to ask their parents for help.
Give him sometime.
Your cousin is trying to manipulate you into giving them the money. Like a three yr old throwing a tantrum until they get what they want.
