Hehe, learn manners? Requirements are dead, people are alive. Actually, it's just talking to people and lying. Just look carefully.

Then I'll use things in my life as an example.

If someone asks your father for help and your father doesn't want to answer it, you should say, "Hello, uncle!" " My father has gone on a business trip. I'll look for him when he comes back. But sometimes when Ni's father is not at home, Ni may say, "Uncle, if you have something to tell me in advance, I will tell you." "

It depends.
