My senior year of high school I went over to my grandparents' house (they lived across the street from my high school) everyday for lunch. I didn't have a class the period right after lunch, but I did have Physics the class period after that. Driving home was too far and so I'd go have lunch, visit with my grandparents, my grandfather mostly since he ran a camera repair business out of his home, and would then take a quick power nap before heading back to school. The following fall I went off to college. While I came back to town a couple of weekends and was able to see him, he ended up dying a month into my freshman year of college. I have always been thankful for that time I spent with him that final year of his life.
I moved back to my hometown seven years after I left it. I saw my family (my parents, siblings, and grandmother) fairly regularly. In 2005 when I had my daughter I started making it a point to spend more time with my family, with the time spent with my grandfather always in my mind. I started taking my daughter (as an infant) over to my grandmother's one day each week. I did the same with my parents. Since we lived in the same city I wanted my children to have a close relationship with my family. And they do. I still go over weekly, sometimes more than that, to visit my now 80 year old grandmother. Due to injury my mother is still here in town (my father accepted a job in DC and left in January. My mother was supposed to leave then too, but broke her foot two days before) so I try to take advantage of the time she is here and take my kids up once a week to see her as well.
I don't really know where I am going with this post except to say that I think if my parents or grandmother were to die tomorrow I would not have any regrets about time spent with them. I know once my mom leaves for DC we will see her less as we obviously now see my father less. Great distances have a tendency to do that. I just want/need to feel like I have done everything and made the most of the time when we live close so that I won't regret it if they were gone...not spending more time with them...and so that my kids never feel cheated or feel like they didn't get to know or spend enough time with their grandparents.
I think one of the follies of youth is that we think we will have forever and then one day we wake up and we are in our thirties with children of our own and realize, "Man, my parents are getting old." While it is not always the most convenient thing to traipse small kids across town for a visit I am glad I make time to do it because my children love it....and so do my parents and grandmother.
