My husband caught a cold and later recovered. I went to my parents' house and said, "He is still alive." Is there a problem with this sentence? Why him?

You used this sentence wrong. There is an unclear generation gap between parents-in-law and young people.

Couples can joke humorously, humorously or mischievously, as long as they don't touch the bottom line of privacy, they will basically live in peace.

But your parents-in-law and you don't feel the same way and can't talk together. You said humorously, "He is still alive"! The original intention is to enliven the atmosphere and say that my husband has recovered, which is worthy of happiness. But in the ears of parents-in-law, it is unlucky to understand that their son is ill, just like you are cursed, so you are unhappy!

The reason why you don't understand is that you lack observation and analysis.

I suggest you read more books, especially books on logical thinking, which are very helpful to you.
