I should have a plaque on my desk that says "whenever you say something happened 'ten years ago' double-check that it didn't really happen in 1997"
@mathowie omg yes, I've needed that since 2015
@mathowie "Were you watching Friends - the first time - when this event happened?"
@mathowie it couldn't have been 20 years ago, I was 12 when it happened... Oh.
@mathowie Someone recently mentioned an album they were listening to was 30 years old, and my immediate mental math is that it was from the ‘70s.

@mathowie

"Dropping a decade" pros call it.

@mathowie As my dad says “1980 was just 20 years ago”
