My 9yo just surprised me. He was deliberatly trying to wind me up. But he said along the lines of: in chess, the king is themost important piece. If you lose it you die. The queens a girl and it don't matter if you lose her. Therefore boys are more important than girls! I am slowly realising that sexism is so ingrained in society, that even my son is picking it up in a simple game. My eyes are becoming more and more open every day.
