Ai Cai's son:
My sister saw your arm with a bandage in the group yesterday. As soon as my mother was in a hurry, she immediately contacted President Gu and knew that you had accidentally misplaced your wrist bones. My mother is also very distressed. Mom hopes you must take good care of your injured arm and don't let it move, lest you can't support gravity and affect your ideal in the future. Now, even if personal hygiene is dirty, try not to move your injured arm.
I will communicate with President Li and President Gu about your current situation. If you need any materials, you can ask other students to help me write them. I'll send you some pairs of socks and underwear, which are not convenient to wash. You can throw it in the past, put the garbage in a food bag or tie it up first, and then deal with it when your arm is ready.
My sister has been busy these two days, and I haven't seen her either. I haven't told her about your injury. Tell her when she comes home tomorrow, and ask her to buy some calcium for you.
All right, son, in short, you should take care of yourself and protect yourself. Remember what dad told you, health and safety always come first.
Mom wrote it in the evening of 3.8.
