Walk the dinosaur
Grandboy (playing a video game where he can ride a dinosaur): Grandpa, dinosaurs were a long time ago, right?
Me: Yep. Long time ago.
Grandboy: I feel like, if I would have been born in the 80s I might have seen dinosaurs then, right, grandpa?
Me: Ayep may have been. You could never tell in the 80s.
