I have a true story about my son.
He got sent a book home when he was 4 and had to draw a picture about something he did during the day. I picked him up at lunch and he was well excited. I told him to wait until I got home and he had a strop about it so I put the book on top of my monitor.
I got home to the news that he had climbed up on my chair and sneaked the book and drawn his picture about some random thing. The picture was completely black and white, scribbled of me, my wife and him - totally desolate and 'annoyed' looking with the use of one colour.
A bright red for our faces.
