Hello Nathan. Can I talk to Mary?
Hello Mark. Mary told me how you helped her out the other day.
Oh! It was nothing,man. I am glad I could help.
But thank you very much. You took a lot of pressure off her.
You're welcome. But it really wasn't such a big deal.
You should join us for lunch this weekend.
