Because I'm a grown up

I don't usually resort to "because I'm a grown up" but sometimes it's true. Lily had put a nightstand on top of her bed which was not a great idea.
Me, "Lily, you need to take that down"
Lily, "Why?"
Me, "Because it could fall on you and hurt you"
Lily, "No, it can't"
Me "Yes, it could fall over and hit you on the head"
Lily, "No, I'll be careful"
Me, "Yes, it can. I'm the grown up, I know better that it could fall. Take it down"
Lacy, "Daddy's the bigger grown up so he knows even better"
Me, "Yes, and he would tell you to take it down"
Lacy, "And Adam & Eve are even bigger grown ups because God made them first"
Me, "Yep"
Lacy, "And God is the biggest grown up because he made himself"
Me, "Yep and he would tell you to take it down too"
