Kids, you can be whoever you want to be as long as you put your tootsies to it.
They say you don't know what it's like to be someone else until you've been in their shoes. I'm not sure who "they" are exactly, or why they seem to know so much, but it's an interesting concept anyway.
It also explains why I was suddenly able to unclog a drain and install a new toilet with expert precision after going bowling that one time, despite having never been formally trained to do so.
Anyway, have your kid slip on a pair of Frozen or Teenage Mutant Ninja Turtles shoes so they can experience what it's like to be an ice princess or crime-fighting humanoid reptile thing, which is only slightly less exciting than being a burly plumber named Joe.
