Asking for a Leave

Excuse me, professor, I need to ask for leave today.

What's the problem, Ruby?

I have an appointment with my dentist this afternoon.

Ruby, you have had three appointments with your dentist this week.

Oh, Professor, you know, the dental treatment is... complicated.

Um... what I do know from you is that it really takes time!

I'm really really sorry, Professor Green.

This will be the last time, I promise.

Okay... your written request for leave?

Oh, I left it at home.

Remember to bring me that with your homework next Monday.

Thank you, Professor Green!

You are so kind. See you!

See you next week.

Take good care of your teeth!
