Why do we have to listen to them?

When we were driving up to Kennecott Copper Mine we drove by the Oquir Mountain Temple and the conversation in the car went like this.

Mom: "Look Justin, there's the temple."

Justin: "What's its name?"

Mom: "That's the Oquir Mountain Temple."

Justin: "Oh, Oquir Mountain Temple. Can I go in the temple?"

Mom: "Well, little kids can only see the outside of the temple. When you are 12 you can get a recommend from the Bishop and go inside to do Baptisms for the Dead."

Justin: "Oh. Why do you go to the temple, Mom?"

Mom: "Yeah, Dad, why do we go to the temple?"

Dad: "Because Heavenly Father and Jesus want us to go to the temple."

Justin: "Why do we have to listen to them?"

Mom and Dad both bust up laughing and try to hide it.

Dad: "Because Heavenly Father and Jesus know what we need to do to be happy."

Justin: "Fine." with a huff and clearly not satisfied with the answer.
