Hey, Robert, what are you doing this weekend?
I didn't have any big plans.
We are putting together a birthday party for Mary.
That sounds like fun. Where will it be?
We thought it would be fun to have a pool party at Jay's house.
Oh good! Can I bring anything?
We will be providing hot dogs, hamburgers, and cake, but people can bring side dishes.
I am assuming that the dress is casual.
Dress casually and bring your bathing suit!
Wonderful. Just e-mail me the time and date and I'll be there.
