More seriously, some people just like older people better. Their interests or personality may make it harder to jibe with people in their own age group, but mesh well with people in another age group. Sometimes they’re ahead of the curve on mental maturity and their peers won’t catch up for a few more years, sometimes they just think they’re more mature than they really are, and sometimes they really would have fit in better if they had been born a couple decades earlier.

Personally, when I was younger, I had a hard time relating to anyone around my age and generally fit in better in conversations with people my parents’ age. As a preteen in the early 2000s, I was reading things like Dune, watching things like Blade Runner, and my music tastes included the Rat Pack. The things the adults talked about were just more my speed. This got to be less and less of a problem as I got older and my current friend group is actually a few years younger than me on average, though I do still have the occasional ‘faux old man’ moments with them.
