If you buy a house, a friend of yours asks you how much the mortgage is once or twice a month, and whether you have paid it back, what will you do at this time?

If you are a close friend, make sure that the other person really cares about your financial situation and tell the truth; If you are a general friend and talkative, you don't have to take it too seriously. Maybe the other party just found a topic and casually said a rough figure, or just said it was the same as last month, or something similar. If a very annoying person asks, you can just say that you won't help me return it. What's the use of telling you?
