What’s something you can’t believe you had to explain to another adult? When I was a kid, I thought adults knew everything. Then I became an adult and now I realize we’re all just making things up as we go. I’m a dumb adult but I’m always up for learning new stuff or being corrected.
The most disappointing example of this in my life is having to explain that dinosaurs did exist at one time to another dumb adult who thought they were a made-up creature.
