My sister-in-law sent me a text message, and what she said was ugly. How should I respond to her?

When he is a child who is not sensible.

Because you reply to text messages, no matter what you say, children will talk about you again.

Even the language is more intense, so that you can't control yourself and swear.

In this way, the child's goal is achieved, and she may speak ill of you with her mother. Do you think the elder sister-in-law trusts you more or is she a child?

Because there is evidence, you will naturally believe the child.

So don't talk to children.

I hope my answer can help you, and I wish you a happy life!
