Your first reaction may be out of nervousness and panic, because you may be worried about being found to have violated the school rules, which is natural. However, once you realize that your behavior is improper, it is normal for you to feel regret.

If the teacher finds you sitting on her lap, you'd better face up to the problem, apologize to the teacher and show your mistakes and misconduct. Then, you can seriously consider your own behavior and school regulations to avoid similar behavior from happening again.

If you feel difficult or uneasy, please ask the school counselor or other credible people for help and support. They can provide professional advice to help you deal with this situation.
