Gavin was be-bopping in the living room last night and out of the blue says "I don't understand why everyone waves their hand high up in the air like this (with his hand waving in the air) for both hello and good bye."
Gavin follows with final thoughts on the subject..."If you want to say good bye it should be like this..." Gavin lowered his waving hand and turned it away from his body. "Just like this so everyone will know if you are saying good bye and not hello."
Why didn't I think of that!
