Who was that kid?

Damn who would have known a week away from mommy and the comfort of home could turn a mouthy little know it all into a decent human being....wow....not the kid who used to live here more than two weeks ago....you can actually talk and reason with him and he hears you, he is considerate, polite, the way others always described how he can be, wow...it was nice to have him home, who would have thought that?
