Absolutely nothing. <3 <3
But explaining to my kid that there's no such thing as Santa Claus was bad enough. He didn't get it. :O I mean it went in one ear and out the other. 4 months later he was telling me all about where the Easter Bunny should hide his candy. Hand flapping, echolalia, jumping up & down...
I shudder to think what he would do if he saw his mom kissing a woman, ya know?
There are some things that are worth the 8000 repetitions to teach him, like reading, music and counting money. There are some things that he just doesn't need to know about. I'm satisfied with what they're teaching him at school about human sexuality. I don't need to make it personal by bringing a partner home right now.
