I think the push, first of all from the truth, as a friend you should regularly active money. Secondly, I urge you to pay back the money so that I have difficulties and need the money and friends do not pay back the money there are three cases, 1: he had forgotten this thing, then I urged him to pay back the money is to remind. 2: the rich do not want to have, this is the default, he doesn't care about your feelings, this bad friend should be. 3: no money is not, if I didn't know he had trouble, by urging him to return money to know his difficulties again to determine the should continue to urge him to pay back the money, so I think the urge friends to pay back the money.
My side's opinion is it is necessary to chase back your money. First of all, as a friend, you should return the money initiatively on time. When I told you to return this money, obviously, it means that I need it urgently. There are three situations claiming why your friend didn't return the money. 1:He totally forget about it. Then, what I am doing is remind him. 2: He got the money but he don't want to pay off him debt. This is an act of repudiation. He doesn't really care about your feelings. Then, there is no reason not to urge this kind of friend for the money. 3: He has no money to pay. I will definitely know he is in trouble when I ask him for the money. Then, I will decide whether it is possible to ask him continually. In conclusion, my side agrees to ask friends to pay off their debts.
