I admit that I was blaming Sidney for the crushed sides on the small pools. I thought she was crushing them as she drained them so that she wouldn't have to pick them up. Today, the real culprit revealed herself. What happens when a 180 pound dog sits on the side of a plastic pool? Nothing, she didn't spill a drop! Sidney looked at her and said, "She is so smart." I agree, dear. I agree.
