Do you have a question, Mary?
No. That's not why I raised my hand. I need to go to the ladies' room.
Let me give you a hall pass for it.
What's a hall pass?
With a hall pass, you can go to the ladies' room or wherever you need to go during class time.
I see.
If a teacher stops you in the hallway, just show him or her the pass.
Or else I'll get into trouble.
