Tom and Mary saw Fred and Sally sitting at another table in the restaurant. Tom went over to them and said, “Would you care to join us?”
•Mary: Isn't that Bill and Sue over there? John: Yes, it is. Shall I ask them to join us? Mary: Why not? John (after reaching the other table): Hi, you guys! Care to join us? Bill: Love to, but Sue's mom is going to be along any minute. Thanks anyway.
