We're learning about the circulatory system. It's interesting.

My back is all cracky...does anyone know what I'm talking about?

I stretch my back backwards and it cracks. It's weird and satifying at the same time. Sometimes I angle my back so that the back of my chair digs into my back and I lean backwards and make it crack. Geez, that was a lot of backs!

My toes are cracky too. I curl my toes up real tight and they crack. lol...
