Magic Mirror?

So, long story short I have a lot of children and they are all girls. In fact, most of them like to pretend that they are princesses. It wouldn't be so bad except that my husband W. Desnay thinks of himself as a king and encourages our daughters to behave like princesses. Well, all of our daughters except for one, Bertha. But I'll tell you more about Bertha later. Right now I'm talking about Sarah, who prefers to be called White as in Snow White.
Today Sarah came up to me and sat on my lap while I was reading through my friend Gertie's blog. Then she looked up at me and started calling me a wicked stepmother. I mean come on. I carried you in my body for 10 freaking months and you're calling me your wicked stepmother? Well, you can't really yell at a five year old when you are in a room filled with people so I calmly asked her what she was talking about. Turns out Sarah had gotten it into her head that my computer was a magic mirror just like the stepmother in her favourite story has.
Now, I am well aware that my flatscreen computer monitor hangs on a wall just like the magic mirror. I am also aware of the fact that I use it to talk to other people outside of my family. But that didn't stop me from putting her in time out for an hour. Of course that just sort of made the idea stick in her head that I was the evil stepmother because their nanny doesn't ever put them in time outs.
Honestly, I don't know how I get myself into these messes. Now I have to convince my five year old that her real mother isn't dead and that I am not her stepmother.
