While we were reading a Richard Scarry book about aircrafts and airports:
Spock: Look the plane's landing gear!
Mommy: It's the landing wheel.
Spock: Landing gear, Mommy.
Mommy: No, it's called landing wheel.
Spock: Prove it to me!
Mommy: (Pointing to the wheel) what's this?
Spock: A wheel.
Mommy: What's it for?
Spock: To land the plane.
Mommy: So, it's a landing wheel!
Spock: But it's not down like a wheel should be.
Mommy: It will come down as the plane lands.
Spock: Alright...I'll trust you!
