Sorry I'm late, Professor Green.
Again? Ruby, it's the third time you've been late this week.
Tell me your excuse for this time.
Um... you know I don't want to be late.
But things come up sometimes. I'm really sorry!
Can't you get up a little earlier?
Actually I set my alarm clock half an hour earlier than yesterday.
But on my way to class, I found I had left my handout at home.
So I had to go back and fetch it.
OK. Go grab a seat.
