Smokey, I enjoy reading the 'younger folks' posts, keeps me thinking; so don't sweat the griping about your age. Follow the other sage advice here & just ignore dip leavins', clean it off & carry on.
Badseed: the cockiness will disappear when one or more of the following happen:
a.) you get older & wise up that it's no way to deal with people.
b.) you get the snot beat out of you by someone who doesn't appreciate the attitude.
c.) you discover that you're not immortal.
Good luck, you'll need it!
