Our two year-old son drew on the wall with a crayon.
I was annoyed, of course, and told him so. As expected, he laughed and drew on the wall some more.
Our five year old daughter immediately came to her brother's defense. "Maybe he's trying to make a Jackson Pollock."
An hour later, she appeared by my side and presented me with her own Jackson Pollock, in case I didn’t understand what she had meant.
