WWOOOOTTTT!!!! Grandkids are sooo much fun. We get to spoil them, take them to fun places and they get to reteach us what a great gift life is. Congrats bud. Live and enjoy. They are truly gods gift for not grinding teenagers to bits.
And so, probably the most amazing and rewarding relationship you will ever have is starting. Your life will become more centered and your view of the future and reflection on the past will have amazing clarity. Happy day !
