Interesting. Is that a reason behind it? I can see why the 2000s might seem like "last decade" (it might still feel like the 2010s), but the 90s are another decade behind...

I don’t really know, but Y2K and 9/11 were fairly notable in a way that most of the other decade transitions weren’t.

I also don’t really know if this is common: but the individual years of my adult life just seem less real than my childhood for some reason.
