Take the initiative to admit your mistake to the teacher and say that you are wrong when you leave school. When the teacher asks you what's going on, you can directly say the reason why you dropped out of school ~ the average teacher won't be too hard for you, and it's not a big problem for you to admit your mistake. At most, I will read you a few words' just listen' when the Tang Priest asks you ~ I promise it won't happen again ~
