Hello, I accidentally started singing while surfing the Internet. My classmates and teachers laughed at me. I'm afraid of what will happen after school starts.

It won't make any difference. Students accidentally open wheat in class, but it is a general violation of classroom discipline, not illegal, and there is nothing to laugh at. Don't care too much. Just correct it later.

And this just shows that this student is lively and active. It is good to learn actively.
