First of all, you can gently remind your friends to pay back the money. In this case, the most direct way is to remind friends directly, but when reminding them, we need to pay attention to some methods to give some hints. For example, find some reasons to lead the topic to the content that needs money. The most common thing is to tell a friend that he has encountered some situations recently and is short of money, and ask him if he can provide some help. In this case, friends are likely to think of things that owe money and return them to themselves, which is also the best result.
Secondly, directly remind friends to pay back the money. You can bring the topic directly to the matter that your friend owes money, although this method is not very euphemistic and tough. However, after all, the two sides are friends, and what they pay attention to is a kind of trust and frankness. If a friend really forgets to pay back the money, it is understandable and forgivable, and their feelings will not be affected after the friend pays back the money. If a friend is short of money because of the current bad situation, he can give some understanding after explaining the reasons, and it is necessary to stipulate the time of the next payment. In this way, I can have a number in my heart.
Finally, you need to be mentally prepared. When friends still don't pay back the money after taking the first two methods and have no time to pay back the money, it can also prove that friends are taking their trust as a kind of capital at this time. In this case, there is no need for such friends to get along, because if the most basic integrity and trust are not met, such friendship is meaningless. In the face of such friends, there is no value. So for yourself, you need to be ready to get your money back.
