Mom: Hey guys! See that bike shop over there? Look at all those bikes!
Meg: Do they have three wheels? Like our bikes?
Mom: No, those have two wheels. You know how Mommy and Daddy’s bikes have two wheels? Well, one day you will learn how to ride a bike with just two wheels, too!
Meg: Why does it not fall over?
Mom: Balance, honey! You have to use your balance to keep the bike up.
Ben: You know what you need to keep a bike with two wheels from falling over?
Mom: Balance?
Ben: No. Two more little wheels.
Mom: Huh.
Ben: Yeah. You buy them in the store.
Mom: Oh.
Ben: And then you attach them.
Mom: Mm.
Ben: And then you won’t fall over.
Mom: I got it, Lance Armstrong.
