Having interns at work who don't remember 9/11, who were born after 2000, and who can drink.
Realizing my little baby sister is 28.
The kids at youth goup played a "recognize the celebrity" game. Out of 15, I knew Tom Brady. One other I recognized by the name after they named him, but I'd only heard about him because I worked on his airplane after an incident.
I still talk about "taping" a show.
I still drive my college car, that I bought new sophomore year. It'll be old enough to vote this year.
I came to the realization that many "old" people aren't "bad at technology" because they can't understand it; rather, they have enough else to worry about that they don't have time to learn it, and even if they did, they don't give a rat's posterior anyway. I'm turning into said "old person".
I sound like a bowl of Rice Krispies coming down the stairs in the morning, with all my joints popping.
I still think of the early 2000s as "pretty recent", and the 90s as "not that long ago"
My five year old called me "boring" ("yes, bud, I am") but still thinks I'm cool ("sorry, bud, I'm really not")
