A Mirror At The Right Height

My nieceroo has been dancing and moving in front of her fireplace ever since she moved into her house. It is a great "mirror", right at her height. Over the time I was doing my j-o-b at their house, my nephew really got into it too. He would dance and move and then run away so his sister could take her turn.
One morning as my nieceroo was doing my hair, my nephew pulled up his bike and started doing tricks on it totally watching himself in the "mirror". He was standing up on the bike, riding sideways, and backwards. I ran and got my camera and hoped that I could capture all that was going on in the mirror and this is what I caught.
