Inviting a friend to dinner.

Dialogue 2 

Laurance- When can we expect you for dinner? Can you
come tonight?
Soony- Not tonight. I promised to go to a concert with
my sister.
Laurance- Well .... How about Friday then?
Soony- That sounds fine.
Laurance- Good. Shall we say seven o'clock?
Soony- I'll be there! You're still a fabulous cook,
aren't you?
Laurance- That'll be for you to decide. I've got a new dish
that I want to try out on you.
Soony- I'm ready. I think I'll fast all day Friday!
