I may be unusual ... as I have learned a lot down through the years from others communicating with me. I'm glad many of these folks that did the teaching through advice didn't take the easy way out and merely mind their own business.
Advice can only be given when there is someone to take it - or at least listen to it and give some thought to it. Maybe that's a bit of a problem these days too - folks not being mature enough to take advice.
Of course when boondocking one doesn't have to give or take advice - for better or worse they're on their own. :)
