Are you doing anything on Monday?
Nothing special. Why? What's on Monday?
I thought I'd have a party.
Nice. What time?
Evening. Nine o'clock. That sort of time.
What's the celebration?
Well, it's my birthday on Saturday, but I'll be away the whole weekend.
Friday's a nice day to have a party, isn't it?
Well, I was going to have it on Friday, but Friday has rather good TV programs.
I know what you mean.
