Couple years ago we ordered takeout the night before a trip, and I was talking to the guy at the front desk about plane travel and how we both traveled unsupervised to meet grandparents in Florida or whatever.
And so I say "yeah it was just totally different pre-911, your parent could walk you to the gate and your grandparent could meet you right at the other gate.
And he goes "ah... yeah... I never got to experience that..."
So I recognize he's younger than me and I says "oh yeah you probably weren't old enough to remember that"
And he says "I wasn't born yet" and when I couldn't hide the shock he was like "I'm 18, I was born in 2004" and gives an intentionally awkward smile and thumbs up.
and then I turned into dust
