I'll tell you when you're older
A grown-up’s way of telling a kid to shut up before they ruin the moment
My mom said that when I asked why the dog was barking at the cat and she was in the middle of her coffee.
My teacher said that when I asked why we had to do a presentation on the moon and I was being annoying.
My friend said that when I asked why his mom was yelling at the TV and he was already late for school.
