During a period in which I worked as an engineering manager, I had to take a 12 session class (one per week for 12 weeks) about managing people. Since I was never really interested in being a manager and eventually went back to engineering, there was only one class that really stood out for me. That class discussed how different generations view the world differently due to what was/is going on in their world during the majority of their lives.
I really saw the differences between the "Depression baby" and "baby boomers" (my generation) when we first bought our condo. At that time, most of the original people were still living there and most had sold their big suburban house after their kids grew up and left home (this was before the kids started coming back home as adults) and downsized to condo living.
One thing I really noticed was the difference in attitude toward money. The "Depression baby" folks generally seemed very fiscally conservative and seemed to not be in debt, while my generation can't seem to borrow and acquire fast enough. I learned a lot from those folks and am not like that at all. We have had some disagreements on our board now that those original people are gone because I want to make sure we have the money for repairs before we spend it (continue the policies of that first group of people), while others seem to want to borrow, borrow, borrow. I also saw the difference in the quantity and quality of the cars, big TVs, etc., again showing the conservative nature of the previous generation.
On the negative side, those first folks were very concerned as people from non-white nationalities started buying into our building. That attitude concerned me, but since the original people are gone, we don't seem to have that problem anymore, with the exception of a very few. I much prefer that people, being human, be welcomed into our community.
What I notice with the younger generations moving in now in addition to the attitude toward finances (debt for everything just seems to be a part of their lives for some reason) is that the big events of my generation are nothing more than something they read about in high school and therefore have little or no meaning in their lives. I realize in hindsight that this is also true for me and the generation that preceded me. For me, WWII was a big deal, but only through movies and reading history. It was totally life altering for the previous generation.
It would seem odd to me if I were in a relationship with a woman from another generation that our respective cultural references would be completely lost on the other. A much younger person wouldn't really know who The Beatles were, any more than I know who Beyonce or Justin Bieber is. To me, such little things are a normal part of communication that form a bond, and that would be missing. Our respective frames of reference would be quite different, and I am not sure that could be overlooked. It is the little things of everyday life that seem to really serve to build a solid bond, and if a lot of that is missing, I am not sure that such a relationship could survive unless there was some other form of inter-dependence to replace it.
Just some thoughts on the age difference thing...
