Upstairs is going crazy, and I don't care if the bathroom keeps leaking. What should I do?

Looking for a property, if the property is the responsibility of the upstairs, you can't deny it, but after all, the neighbors upstairs and downstairs can't be too stiff. If your roof leaks, you can reasonably ask for compensation upstairs, which is necessary. If you refuse upstairs, it can only show that people are poor and have no choice but to enforce them.
