I will tell you a story when I first started at primary school...
The teacher noticed that I always painted in black so she was concerned. She spoke to my parents of her concern and together they felt that I should see an Education Dept Psychiatrist as it was felt that I had some very dark issues going on in my brain. After about 4 sessions at the Psychiatrist's clinic they put me in a room with a 2 way mirror. In the corner were a whole lot of paints all in different colours except there was no black paint. Apparently I am told that I lost it and screamed and cried. The plot thickened as they couldn't work it out. They tried again except they included the black paint of which I happily went over, grabbed the black paint and started painting.
To cut a long story short and after about 8 sessions they finally worked out what that sinister black paint issue was in my brain...
In the classroom I sat the furthest away from the paints so when it was paint time by the time I got to the paints, black was the only one left!!!!!!
Fantastic Education Dept Child Psychiatrist at work...I was moved closer to the paints where I happily painted each day in different colours
