Logic and connections

When I was a little girl, I truly believed that all dogs were male and all cats were female. It seemed impossible that you could get female dogs or male cats. I have never mentioned this to the children, so I was interested in this little exchange with Bright Eyes yesterday.

Him: "Do boys like dogs? Can they play with them?"
Me: "Girls like dogs too. All children can play with dogs if they want to."
Him: "No. Girls play with cats."
