"Send lawyers, guns and money. The shit has hit the fan." - Warren Zevon
As you so astutely put it, John Paul, grandfathering can take a lot out of you even to the point of leaving you utterly exhausted and begging for sleep! God has a way to compensate grandfathers for their work: Olivia Grace will infuse you with so much unconditional love and affection that you will never say 'no' for any opportunity to offer this labor of love entrusted to grandfathers. Enjoy every single minute of your time with her.
Enjoy the time, it IS precious! And congrats, Grandpa!
