Managing finances properly is key to our financial life, which is well known to each of us, I guess. I feel like this is in my bones so sometimes I make some decisions subconsciously. I recently ran into a situation where I found myself really awkward. Last July or August(I can't remember that clearly), one of my extended family cousin asked me for three thousand dollars as he lost his job and could not pay off his loans. I refuse to lend him the money cause I knew him well that he was not a solid trustworthy guy. A few days ago we met on a family reunion occasion and he did not really talk to me and I suddenly realized that it was because I didn't lend him money last year. I think about it twice and if he had not been that untrustworthy, I would have definitely lent him the money. Anyway, I hope he is doing fine now and best wishes to him.
Three thousand dollars is not a small money except you can afford to lose it. When you are dealing with money you don't consider relationship. You should only do business especially loans to only trustworthy and reliable people. If you know your cousin will not repay the loan don't give him except he offers a collateral. if he likes let him be angry that's his business because it is clear that you didn't offend him. If he really needs the money, let him approach a bank or other financial institutions.
OP why did you conclude that he is not trustworthy? Have you or someone else given him loan and he defaulted? Is this an established or based on hearsays because it is also good to assist people when they have financial problems.
