(Students are required to show their student ID cards when borrowing a book. Two students walk up to the front desk.)

Student #1: “Hi, I’d like to borrow this book for my friend here.” *hands me their student ID card*

Me: “If your friend would like that book, then she needs to bring her own ID card and borrow it herself. I can’t let you borrow it for her in case she causes any damage or loses it.”

Student #1: “Oh. But she’s very responsible. She wouldn’t damage or lose it.”

(I turn to the second student.)

Me: “Where is your student ID card?”

Student #2: “I lost it.”
