My sister and I are only 18 months apart in age. My kids are quite a bit older than hers, though. My kids grew up with my parents pre-traumatic-brain-injury. There is a difference.
When my kids were growing up, my Mom and Dad would come and visit us in upstate NY. My Dad would always ask for a volunteer to go with him to Wegmans. Without fail, while in Wegmans, they visited the HUGE bulk candy section and came back with HUGE bags of candy for everyone. It was special because it was just my Dad and one of my kids at a time going on an adventure. My Dad still talks about those trips to Wegmans.
My sister's kids are young enough that most of their memories of my Dad are after his traumatic brain injury. My Dad no longer has a driver's license, so he can't just take one of my sister's kids to the store or to Burger King or to look at birds in a favorite spot.
Today I got to take my niece and nephews to Wegmans and show them the HUGE bulk candy section. It was a big hit. My Dad wasn't there, but it is still part of his memory. I called my Dad and left a message letting him know that his grandchildren got to experience Wegmans' candy section. I know it will bring a smile to his face and now Jen's kids share in this Pop Pop memory just a little bit:-)
