Me:  You sound happy

Mother:  All the girls are round

Me:  Ah.

Mother:  Just a little get-together

Me:   Nice.

Mother:  Yes.  So.  What've you been up to?

Me:  Tell you what - why don't you get back to the girls and I'll speak to you later, maybe over the weekend?

Mother:  Tomorrow?

Me:   No, the weekend.

Mother:  Well, maybe tomorrow.

Me:  No, definitely the weekend.  I'm busy tomorrow.

Mother:  Oh - Alright.
