Theoretically, it shouldn't be with. I usually go out to eat, and my younger brothers and sisters who don't have internships can't count money. If you follow, it will actually encourage the wind of comparison, which is very discouraged. But they are all friends and don't look up at each other. People have done it, and it makes no sense for you not to do it. If that's the ethos in your place, don't force it. I tell you, if you are reluctant to give, or don't want to give too much, you'd better ask others quietly how much they gave, and then you can reduce it by 100. When you find a classmate who works, you can seriously say: buddy, our family is not very rich, and I am not too disappointing myself, you know. But my family won't help me. I stood up this time, save a province and get together. It's a little missing. Please don't take it personally. Keep it.
