Nice to see you, Mary! Come in, please!
Thank you Tom, but I am afraid not now. I've come only to return the book borrowed from you.
Wonderful. I've been waiting for you a long time and longing to know what you think of it.
It is very interesting and I've learned a lot from it.
Well, so it is with me.
Oh, sorry. I can't go on talking about it with you any longer.
It doesn't matter. Better stay here for another 10 minutes.
No, I'll go and buy some food in the shop and I have to say goodbye to you.
