On: Teaching is a slow process of becoming everything you hate

The quote isn't about his temperament but his knowledge, so I think that interpretation is a bit of a stretch.

I think the same kind of quote would absolutely apply in exactly the same way to temperament though. The 14 year old thought his dad was a jerk who mellowed out by the time he was 21, the reality again being that the biggest change was actually the child's temperament.

Or it could have the same tongue in cheek sentiment. It's a lot harder to beat the crap out of a 21 year old than a 14 year old.
