Boy howdy, you said it .
I lived the idiot life and didn't realize how little I know until I was in my late 40's..... (insert red faced emoticon here) so I too try to gently teach my foster boys before they get side swiped or sand bagged by those insecure idiots who are always on the lookout for someone who's not as 'hip' (or whatever) as they are then make a big deal out of embarrassing them in front of others .
Me, I don't much care so I'm hard to embarrass, this allows me to turn it 'round on those rude folks when I want .
Fifty was pretty good for me as was most of my forties .
There are _so_ many I wish I could apologize to now

nothing on me ~ not a thing I'm proud of .
