Don't worry Mark!
From what I hear you still have about 6 or 7 more good years left where you'll still be viewed by them as a "hero" or at least a pretty good guy anyway.
After THAT, get ready to be viewed as the biggest jerk in the world who doesn't have a clue about how the world "really works".(that is of course until they move out on their own, and then suddenly you're A-Okay again)
"When I was 16, I thought my father was the stupidest man on the earth. But when I was 21, I was amazed at how much HE had learned in just 5 short years"[Mark Twain]
