Twinkle Twinkle Little Star

While in houston I went to the neighborhood pool for a swim. I went to the bathroom and was in the middle of doing the duty when I heard the voice of a small girl talking to her dad in the stall next to me. I didn't know what to do. What was I suposed to do? What is my duty in a situation like that? If I had know that the child was in there I may have waited to start until after they had gone. But it was too late. Once you start, you can't stop. It stings. Was it my fault in etiquet, or the Dad's? Should dads take their daughters into the mens' room, or is it soley for men? I think they should have a special bathroom for families. A one room, lockable bathroom where parents can take their children without worrying about having to explain why that man can go to the bathrrom standing up and she can't. It should be done.
