Sharing my failures?

Here is an interesting video I recently found. I am aware of the fact my kids are always watching me - not necessarily proud of that fact and perhaps some of the things they see that I could do/be better - but the idea of sharing my failures with them was new to me. Sure, it's one thing to say, "Yes, Daddy is being disciplined by the police because he was speeding!" but a whole other thing to share real failures. That would constitute "Charles' deepest darkest secrets, fears & anxieties" and only 24% of you wish to hear about that, therefore, why would my kids want to know? Hmmm... what do you think?
