I refer you to the book "Show Me" and others like it published in the 70s to teach sex to children. They were filled with photos like that and were recommended by many Christian groups and churches at the time.

Right. I wasn't even trying to get into that sort of thing, though.
The bathroom photo was perhaps taken by a kindergarten teacher or a parent beause its caption says something like, "Can you do it all by yourself?" And that clearly shows what it was meant for, which is to keep the record of the growth of children and celebrate them. We use cameras to do that, and we create photo albums.
Life is good and beautiful, you know, but I guess I sometimes tend to forget why I started taking pictures in the first place. So, this particular photo was a good reminder for me.
