I quarreled with my classmates. I don't know where I am wrong. Ask for guidance, how to apologize!

It's normal for students to have contradictions, but it's not normal without them! Calm down first. Sometimes the louder the noise, the better. The real problem is not noisy! It's better to have a quarrel than two things! Don't worry! If you are embarrassed to apologize in person, you can choose text messages or letters! I think as long as you sincerely apologize, the other party will accept it gladly!
