Claire:  Yes, we've a wide area to cover! (Saying angrily to Mike) I don't suppose you would like to join us! But not too busy to come to my house for snacks! (Saying to Bob) Face it, Bob! Your buddy is a user!
Bob: Mike has redeeming qualities!
Claire:  Yes! Like he belches to let you know he appreciates your food!
