A girl, a scheming bitch, spilled boiling water on my monitor. I'll tell you how to write, and try not to use too many dirty words.

Because everyone doesn't know your real situation, it's better for you to think for yourself, and what you write is just to vent your anger and can't teach the girl a lesson. Of course, it is wrong to teach her secretly. Otherwise, what's the difference between you and a scheming bitch, right? Your hands are dirty. The spilled boiling water is very serious, so you should report it to the teacher and the principal in time and ask them to explain it to you. Of course, you should also ask your monitor to see a doctor or face it. You can warn her appropriately.
