What if there is a psycho living upstairs?

He lives his life and you live yours. As long as he doesn't interfere with you, you'll be fine. If he likes mental derangement, he will have mental derangement. He is not your special person, so you don't have to pay for him.

In fact, the most important thing between neighbors is harmony. Can you keep others out of it? If you can, try to solve it yourself.

If his behavior interferes with you, you can go upstairs and communicate with each other. The other person is not really crazy, so he will value your suggestion. If he ignores it, doesn't he still have family? Communicate with his family. His family can't all be crazy, can they? If so, isn't there a community? Reflected in the community, this situation should not be that your family is affected, and it is difficult for other neighbors to be affected more or less. It is most appropriate for them to intervene in supervision. If the above methods can't solve the problem, and 1 10, you can call the police. For this disturbing behavior, the local police station should be able to help.

If it still doesn't work, then move, sell the house and go out and buy another house. So that everyone can live in peace.
