LOL, that's funny Claudia!

I don't remember when I found out either. But I have an older brother and sister so I'm sure they told me at some point.
One year we (for some reason) had Christmas on Christmas Eve. And my parents said they were going to get Santa to come early. We had to stay in another room with knit ski hats pulled down over our faces (don't worry we could breathe). But what my parents didn't know was that I could see through it. So I watched them carry presents into the front room. LOL Oh well. It was still a good Xmas.
