This evening my little girls learned a new game. It's called Bonzai.
The rules are simple, really. I lie down on my bed, stomach down. The children take turns standing on my back. As they jump off me like the five-foot spring board I am and onto our super-bouncy bed, they yell, "BONZAIIIIIIIIIII!"
That's it. That's the game. Over and over again. I am quite sure my back will be several shades of blue by morning.
