I was telling someone much younger than myself that airports didn’t always completely suck to go through. I explained how the TSA wasn’t a thing and the experience was closer to getting on a bus or a train pre 9/11.

He had a hard time wrapping his head around it because he’s never experienced it.

Made me feel very old.
