I think when I moved from not liking things younger people enjoyed to simply having no idea what they enjoy at all.

I've never been particularly with it on trends and such. When I was younger I knew the trends and rejected them in the spirit of youthful rebellion, aspects of my personality were defined by what and who I wasn't.

Then I got a little older and rejected the things people slightly younger than me enjoyed. This came naturally, because I was no longer the target audience for these things it was easy to write them off as if I were.

Now I don't even know enough to reject them. My knowledge of what younger people like seems to be about five years out of date. When something new comes along that seems irritating to me it seems to pass so quickly I don't really have time to register it, and when I find something new I enjoy there's apparently whole fandoms about it where (presumably... hopefully...) very young people fight about it, and they're fighting about things I genuinely don't have time to decipher. It's like it all moves too fast for my vision to really gain focus, by the time I'm able to tell what I'm looking at everyone else seems to have already moved on.
