The child inventing a game uses the park differently from the adult admiring its plan.

A designed space and a used space are two different things. Adults tend to evaluate the layout, the materials and how it all fits together, while a child treats the whole thing as raw material for a game that will be invented in the next four minutes. Neither view is wrong, and only one of them is actually playing.

Watch how something you are proud of is genuinely used before deciding whether it worked. Judging it by the plan tells you about your intentions, and judging it by the use tells you about the thing itself.
