Lovely story! I think it's awesome you went there to spend time with him..
I know how it feels to be the only grand child that visited for company reasons just to be with the grandparents she loved, compared to having nieces and nephews that only came to the door to pick up their allowance and leave right away. I never understood how they could do that. So rude.. but that's the difference between me and them lol.
Your story made me consider entering the contest, I guess I have plenty stories, and it would be nice if at least one of them is to be found on the chain forever :)
Enjoy the weekend!
