history: I let my life time best friend borrow $10,000 so he could get a vehicle to get back and forth to work. My best friend lost his car to an accident that wasn't his fault_comma_ so I lent him $10_comma_000 to buy a used vehicle so he can get back and forth to work. I'm confident he'll pay me back like he promised. You are very trusting. I'd just assume give my kidney to someone as 10k.
current: I know that he needs the money more than I do right now, and I do trust he will pay me back as he says. I just wanted to do what was right.
next: Your better then I am. I hope you don't learn a lesson the expensive way.
