There is no doubt that the teacher did something wrong. No matter what reason the teacher has, even if he has agreed with the students that he can smash the mobile phone illegally, he has no right to dispose of other people's private wealth in practice.
Although classroom teaching should be a matter of mutual respect, at present people prefer to regard teachers as service providers. There is a jargon in the service industry: customers are God. There is also a saying that the service industry is the standard: customers are never wrong. If I find that the customer is wrong, it must be my fault. If I am not mistaken, it must be my fault that caused the customer to make a mistake. If it's the customer's fault, it's my fault as long as he doesn't admit it. If the customer doesn't admit his mistake, I still insist that he is wrong, which is even more my fault.
What seems to be smashed is your mobile phone, which actually makes more students tremble and stay away from it. The question is: does he have the right to dispose of other people's wealth? Obviously not.
I think the cultivation of self-control needs to be separated from the inside and outside, and external assistance is needed when the internal force is small, which was always the case before college, not to mention that some college students are still immersed in games and drama. So try to get to know your teacher first. Anyone who makes a decision is thoughtful. After all, the starting point is good. If the mobile phone is smashed, you have to pay for it. Teachers will never be stupid enough to spend money to provoke public anger. If you don't understand, talk to the teacher again and see what the teacher thinks. You will understand.
People under the eaves have to bow their heads. You are using your mobile phone against the authority of the teacher. It is really wrong for the teacher to drop your mobile phone. Do you think he can do anything? The best thing is not to take the phone and endure it.
I don't think this can go online. What do parents send their children to school for? Isn't it just for success? How about strict management? I don't think it's a good way to deal with it when you repeatedly advise me not to listen to it while playing with your mobile phone. My parents weren't so strict before? I'll hit you when I say I hit you, and I'll tell my parents that I hit you again when I go home.
