Ben in 3 hours...
DAMMIT! WHERE'S THAT NOTE?
I've just realized that having children is God's way of preparing you for old age.
While you are young, you can put something down and have it disappear at any moment because of little fingers forcing you to search all over the house to discover where it's been moved to.
Once you're old, that skill of finding where some person (you, this time) hid the item becomes very useful.
