It's likely he got the idea from someone else's life. My Dad, though a genius, doesn't have many original ideas. And, really, when it comes right down to it, he doesn't often execute his borrowed ideas very well.
We didn't have much of a relationship. The main time my Dad interacted with me was to punish/discipline me or to hit my leg when he thought something was funny while we watched TV together. Seriously.
So, I wasn't too excited about the prospect, but yet... I was totally excited. My Dad was taking me on a date. My first. He told me he wanted me to know how boys should treat me, so he was taking me on a date to model what I should expect. I'm sure that effort would've been more successful if I'd actually valued myself at all. I didn't, which I'm sure is a result of generational curse stuff as well as not feeling like my parents valued me much at all.
