"You have to respect your elders!" I teach my kids that up to a point. Looking back, as a young man, I was very very respectful to people as I am now and especially people much older than me but on a few occasions when I was younger, I was, unjustifiably, treated very disrespectfully by a few older adults that I should have clearly whipped their arse as they were in the wrong.

It doesn't matter how young a kid is as long as the kid is "respectful"... that kid deserves to be treated respectfully. If a retired GW blocked me in and could not show proper ID, which I would respect the law, but if he can't, I am personally going to move his truck out of the way or one of us is going to get his arse kicked.
