I don't know why the instructor is targeting you, but if you and my buddy are in a similar situation, they are talkative, controlling and rebellious. Especially when the instructor targeted him, he instinctively "hit back" the instructor. Occasionally talk back to attention, often play around and deliberately don't cooperate. If so, frankly speaking, you deserve to be targeted by the instructor. But as my good friend, of course I want to help him and give him some ideas. Maybe these ideas are helpful to you and can give you some reference value.
Idea 1: Pretend to be sick. At that time, my classmates often went to the school doctor to get glucose, but it seemed that it was okay to lose too much, and they could also write a note. But you can't do it often, otherwise it's too fake and the school doctor may not be willing to cooperate. Therefore, there must be a second plan. The second plan has some "bad ideas", that is to say, kidney is not good, that is, the legendary kidney deficiency.
You can tell the coach that your kidney is damaged on the grounds of illness, nephritis, long-term medication and excessive fitness. In short, kidney is not good is used as an excuse to reply that instructors can't stand for a long time, and standing for a long time will cause obvious discomfort. The general instructor asks you to issue a certificate. As long as you do, you don't have to participate in military training. But what if the problem proves that it can't be opened? Find a class teacher to coordinate and achieve the purpose of participating in military training according to one's ability. If parents need to call the teacher, they can ask relatives to make this call on their behalf. At first, my buddy asked his friend's father to be his guardian and communicate with the teacher. In the end, the instructor completely chose to "indulge" countless him in military training. Although this method is somewhat detrimental to the reputation, it is really useful to deal with your own instructors.
