What kind of wonderful classmates have you met?

Borrowed socks and a washbasin once. I wondered how I could use this personal item casually, but I was embarrassed to lend it to him. I get bored after borrowing it a few times. As a result, he washed his face with another footbath. As a child in the north, he was deeply shocked. He didn't buy paper for one semester, but I used paper for two semesters. When I finally couldn't afford it, I took some paper to hide for myself. It is also a semester to rub my net, not paying the net fee, and even not wanting to buy water. Every time I buy 1.5 liters of bottled water, he picks it up and drinks it. He has told me many times, but he still won't change. Every time he drinks it, I dare not touch the water again, which is particularly wasteful. In the end, I had no choice but to buy 550 ml bottled water. I dare not drink now. He has a pair of shoes of 600 to 700 and a tennis racket of 1000, which makes me dumbfounded, but he never buys small things for his own use. Such an excellent person has found a girlfriend this semester. He calls his parents as soon as he has no money. I don't know how embarrassed he is.
