There was a classmate's birthday in the dormitory next door when the freshman started school. Our dormitory and the dormitory next door are in the same class and major. People in their dormitory invited us to have fun together. Although we have only known each other 10 for more than a few days, we have never looked up and seen each other since. Well, we went to join in, that is, eating cakes, drinking beer and licking spicy strips. We didn't feel very happy that night. The next morning, people from their dormitory came over and asked us to pay, saying that they would share the cost of last night's birthday party. At that time, we were very embarrassed ... Later, the poor students in our dormitory always scolded the students who had had birthdays as "worthless" and had no money to hold birthday parties.
