This reminds me of the time I took DS age 3 to buy his first ballet uniform after his trial class. He was very quiet as we measured his feet and tried on the leotard and shorts. As we waited to pay he tugged my sleeve and said, "But mummy, when do I get my ballet skirt? Everyone else in the class was wearing pink skirts, why do I have blue shorts?'
That was the day he learned about discrimination...
