In our school, if students want to go out of school for some time during the day and come back to school, they have to ask their teachers to issue them a document or pass to prove that they got the permission. How do you say this kind of paper? Suppose it is called 'AAA,' is the following conversation OK? Student : Ms. Shin, I'd like to do some bank work at luchtime today. I need to send some money. Could you issue 'AAA' to me? Teacher : OK. Be back before the 5th period.
