Today Emma's gym class gets to swim in the pool. On the drive to school she told me they're going to teach them how to dive.
"I think I already know how to dive, I just get nervous," she told me.
"You do know how, and once you get comfortable with it you'll never be uncomfortable with it again. It's sorta like riding a bike, you know?"
There was a long silence in the car.
"I don't know how to ride a bike."
When she said it, it startled a laugh out of me. "Yeah, bad analogy. Sorry about that."
