My parents completely hid all finances from me and my sister growing up. My mother in particular would be horrified to think that their kids were stressing out over mortgage and utility bills. They didn't have to sit down and show us their pay-stubs for us to know roughly what types of things we could afford though. Perhaps if my parents had been really wealthy and could afford anything, then I would have grown up with no concept of money. But, as it were, I had a small allowance that I could spend as I pleased and I knew pretty well what price range we could afford for birthdays and such.

I would like to think I'm a moderately successful entrepreneur with a decent ability to manage personal and corporate finances. I'm thankful I didn't have that "adult" stress on my shoulders and was allowed to just be a kid.
