Grandpa's speech is so irritating. Said a rude word to him, menstruation also no matter, dumped him a slap in the face. What happened?

To save face, in fact, the best way to talk to elders is to reason with them.

Talk more about your difficulties. Generally speaking, an elder speaks badly because he keeps talking about your mistakes.

Simply put, I want you to reflect on your mistakes more, so it's ugly.

Tell your elders more about your difficulties and admit your mistakes, even if you didn't do it yourself. You should also accept that mistake. In this way, the elders will not say much. Only in this way can we go on and solve things. If it's really not your fault, you can't refute it or say anything. The elders have said enough and are proposing solutions.
