I've actually wondered about this very topic for some time. Not only does she know, support it and encourage it, she often gets me cards from my wish list for birthdays and Christmas (I can see the slabs now under the tree.
C'mon red Cobb!?!?!?)
As far as the amount of money - she knows that I never spend what we don't have and that some of that "shit down there cost you tens of thousands of dollars."
So, yeah, I am pretty lucky!!
