Erica: I've sent out the invitations for the dinner party.
Manuel: That's good. Now what should we do?
Erica: We've got to plan the menu.

Erica: I think I'm going to make the chicken salad we had at Pompa last time. Remember I asked the chef for the recipe?

Erica: Thanks! I think I'm getting old!
Manuel: Looks like you ARE!
