You're supposed to play with crayons.

They draw with crayons on the wall.

You each are given an identical strip of blank paper and begin coloring parts of it with crayons.

So I wondered what would happen if we remove all those words and hand it to some four year olds along with some crayons, and don't say anything.

I was an introverted child, to the point of communicating with colored crayons and apologizing to objects when I bumped into them, so my mother thought it might do me good to write down my day to day experiences and emotions.
