My wife and my old man (and my father-in-law) have been rumored to have some scandals. How to deal with this situation at present?

Did you see what happened to your wife and dad? If you have doubts, tell them the rumors outside. It's okay, just a reminder. If there is anything, you can guess a thing or two by looking at their expressions and actions. Advise your mother not to entertain foolish ideas, and don't take things that have disappeared seriously and add chaos. If something really happens, it's up to you.
