Lily: Mom! Can I wear this earring?
Lily: It's the kind you just clip on, so I can wear it.
Me: Because last time I let you wear those they made your ears bleed.
Lily: [shrug] .... So.
Me: So I'm not going to let you wear earrings that make your ears bleed.
Lily: They're my ears.
Me: Not until you're 18, they're not.
I have a feeling I'll be having this conversation about a thousand times between now and 2021.
