I sometimes find the biggest "generation gap" I have is with people my own age, because I'm not in the same place that most of them are. I'm in my late 50s (59 next week), and while I am married, I married late (at 40), so no kids, don't own a home, etc. Most people my age will talk about things like their kids being at university now/graduating uni, getting married, them becoming grandparents, doing home repairs, etc. and I just think "weird", because it's so far removed from my reality.
