My son was cheated for the third time. Should I call him stupid?

How on earth did you cheat? Generally speaking, you must tell him, not only scold him, but also enlighten him, and then analyze the reasons why he was cheated to prevent being cheated again.

So many people have been cheated once, and they will remember it for a long time next time. Generally speaking, they don't say that they are stupid enough to be cheated again and again, and that is really hopeless.

As the saying goes, you learn from a mistake. Like now, children are not as profound as society. He doesn't know how to deal with complicated interpersonal relationships in society, so he is easily deceived. As someone else, you should tell him some anti-fraud skills and some cases in social life.
