This is the conversation that my dad and I were trying to have with my son:
Me: So, I'm your daddy, but he's my daddy and your grandpa. You're my son, I'm his son and you're his grandson.
I'm pretty sure he got it.... eventually :-)
Moments like these are precious because as we all know, time waits for no man. Years from now, it will be cool to look at this picture and fondly reminisce.
