I believe that you called me?
Oh, hi. Thanks for getting back to me quickly.
Why did you call me?
I was calling about your son.
Did he do something wrong?
Your son was acting up in class.
What do you mean?
He was talking and causing a disturbance during class.
That's really not like him.
If you could just talk to him, I would greatly appreciate it.
I apologize, and I'll make sure he doesn't do that again.
Don't worry about it, but thank you very much.
