Today, me and my dad went to the local gym. I did one hour on the running machine and burned 400cal. After that we had a rest and went swimming. The water was very cold but we still went in. I bumped my leg on something and I looked in the water. There was a big blue thing that was making a sound. Just then two men came in and told us to come out. They said that they were putting new clean water in. So we came out. Just as things couldn’t get worse I stepped on a slippery tile and slipped right on my butt. It was very painful but when I got home my dad said that I hit my coccyx, which is the hidden tailbones in your butt. I think that I broke it. Sitting down is painful. Standing is better, but bending is the worst.
