Heh heh, takes all kinds... For some, lessons are better learned the hard way when they don't want to listen to reason.
Sure, we were all newbies at one point or another, and most of the time common sense prevailed.
If we didn't get it right the first time we figured out why and re-did it. We asked, we read, we learned and got better. That makes us much safer, if not smarter . So when people brush off good advice and common sense, all we can do is smile and say, "Good luck with that eh."
