Throw The White Crayon Out

I was sitting down with Son to make sure he was coloring correctly for his homework. As he dumped the crayons out of the crayon box, he told me, "Mommy, this white crayon doesn't work. I tried it at school. Throw it out."

I immediately knew he meant that the white crayon doesn't show on paper. I explained to him that it is for colored paper.

He said, "Oh."
