I have a younger brother. We don't talk. We did. I just got sick and tired of having the same conversation with his drug addled brain.
He has a son, whom I love as much if not more than my brother, and less than his father loves him. Son, like father, are wake & bake. Neither can get out of bed without a smoke. Brother attended AA religiously. At least a third of his AA Chapter were wake 'n bake.
What fascinates me about my brother is he has no interest in learning from our ancestors. One of our ancestors was Bradley. Brother makes the identical parenting mistakes as Bradley. If he could see that, would he want to? If he wants to he can.
