"From the lips of children and infants"

Yesterday morning at kindergarten I was sitting at a table where four children were playing with Play-Doh and there happened to be an extra mat on the table. This became a topic of conversation when others came who also wanted to play and were turned away with the reminder that the rule was four children to a table.
Little Boy #1: But there are five mats...
Little Boy #2: One of them is for parents here.
Little Boy #3: Yeah, like Miss Lisa.
Little Girl: Miss Lisa isn't a parent.
Little Boy #2: Oh yeah?
Me: No, I'm not.
Little Girl: Yep, because she's young.
Me: Not compared to you I'm not.
Little Girl (Sounding knowing, like sharing a romantic in-joke, and yet matter-of-fact like that's-the-way-it-works): When you find the love of your life, then you'll be a parent.

It was one of the funniest things I'd ever heard.
Once in a while I wonder why I still get up in the morning and slog through the slush to go work with six-year-olds who scream, fight, and occasionally swear.
Then one of them reminds me.
