actually, I don't think it's necessary to put the friendship between your classmates on edge for 2 yuan. Besides, you don't have to go to other people's homes to ask for debts on New Year's Day. You know, it's bound to embarrass others. In fact, you can choose to find an opportunity after the New Year, and then ask him out for dinner. Talk to him euphemistically about the matter of owing money at dinner. He may be particularly difficult at home and can't come up with this 2 yuan. You can give him more time to prepare for another 2 yuan.
