"When do you think you will pay me back the money you own me?"

VOA: special.2010.06.26

if your friend asked to borrow $100 from you, ... you would probably not say-- you might actually put interest on this person, so you could say, alright, I'll do it with 5% interest, pay me back in a year.

你的朋友向你借100美元，你可能不会说-,你可能会对他收取利息，因此你没准会说，好吧，我要收5%的利息，一年之后连本带利还我。

Moreover, if you say, this stockbroker he was lying to me, he told me that this was a good investment and he even lied and said something to get me roped in, they won't pay you back.

再者,如果你说,股票经纪人欺骗我,他说买这个股票是个好投资,他对我说谎,把我骗迷糊了,他们不会还钱给你
