I’m a graduate student in the US, and to make enough money to pay for my rent and food, I have to work as a guard at the university library at night. Last week one of my friends, Lin, came to the library after hours. He told me he had left his notebook in the library and needed it to study for a test the next day. I told Lin that according to the rules I was’t supposed to let anyone in, but he begged me and said that if he didn’t get his notes there was no way he could pass the test. He was my good friend and I knew he wouldn’t steal anything. I also didn’t feel like I could say no, so I let him in. Unfortunately, just then my supervisor came by and saw Lin going in, so he stopped Lin and then started bawling me out in front of Lin for not following the rules. I tried to explain the situation, but that only seemed to make my supervisor more angry. He said it didn’t matter if Lin was my friend or not, so I just shut up and let him scold me. I realize I broke a rule, but I know Lin and trust him, and letting him in wasn’t the same thing as letting in a stranger, I think my supervisor was very unreasonable to be so picky and critical, and I don’t think he should have yelled at me, especially in front of Lin. Why could’t he understand why I let Lin in?
