Can't say like that lah, she borrowed the money to you, that is
a kind deed, it's your duty to return her, even if it's 10 cents.
It's her right to ask the money back. It may not be alot of money
to you, but you can be surprised how $10 means to alot of poorer
people, it could keep their stomach full for 2 days. Do you have
any idea how feeling hungry and not having the money to get food
feels like? I tried it, just to experience real hunger, and I tell
you, after 1 full day I give up, I cannot stand being hungry. I
guess I'm getting my point across.
