I am a 15 girl from physical education class this afternoon. I wore a pair of New Balance PE teachers insisted that I didn't wear sneakers and told me to take off my shoes. After a while, he looked at me.
This kind of teacher is of low quality, too overbearing and improper educational methods. First of all, whether these shoes are sports shoes is a matter of opinion. I think they are sports shoes. Secondly, slippers arrive at the penalty station in time, not counting sports shoes, which belong to corporal punishment of students and improper education methods. It is recommended to communicate with parents, but if it is not possible, go to the Education Bureau to complain.
I hope this will not cause you a psychological burden. You didn't make any mistakes.
