My father-in-law has the habit of criticizing others. What should I do?

Move out if you can. Otherwise, you can't pretend to hear. Women can't be the same after marriage. Your father-in-law is like this, which has become a buffer for the contradiction between mother-in-law and daughter-in-law. Having a naughty mother-in-law is really more terrible than a sissy father-in-law. It is a magic weapon for married women to be confused.
