Libby likes to swim. We have gone two days in a row to the pool and no one else is ever there. She does laps with her head down and her back curved over because her spine is curved. She wants to improve her strength. We come back and change and then take the dog out for a walk. Yesterday she fell. We were tramping along the grass with the dog and her shoe hit the lip of the sidewalk and caught and she went down. She didn't hurt herself badly but she does have an abrasion on her knee. It was scary. Today I will have to be more vigilant.
