This falls under the category, you know you did things as a right as parent when . . .
My daughter sent me the following:
In 1346, Francesco Petrarch, an Italian scholar and the "father of humanism" wrote:
"I cannot get enough books. It may be that I have already more than I need, but it is with books as it is with other things: success in acquisition spurs the desire to get still more."
It was true in 1346 and it's still true in 2009.
