Today, in class, a boy was very naughty, so I asked him to stand up as punishment. As a result, he didn't sit down, so I made him stand up and cry. Speak in a nice voice

His performance shows that he is not satisfied with your punishment. You can ask him more about the details. What is the reason for the punishment? He speaks in class. Fighting with others? So the main reason is because of him? Will someone just hit him, and you just saw him when he called back, thinking that he was naughty and let him stand as punishment? Of course, this is only a hypothesis, because what people sometimes see is not necessarily true, so we must find out the real reason. If he is really disobedient and disturbs the order, there is nothing wrong with standing as a punishment, even if he cries, let him stand.
