Stupid question

I just bought Esme new shoes from an online children's shoe shop. All they sell is children's shoes. In fact, they're called Shoes 4 Children.

Part of the checkout process was the question, "What was your reason for buying?"

How many reasons can there be? Somewhere, a child needs shoes. You sell children's shoes. You don't sell anything else. Shoes have only one purpose.

I wrote I am hungry.

The End.
