Maybe everyone would feel better if they used a clear shower curtain and locked the bathroom door, and secured their premises before they shower. I like clear prism curtains because you can see figures that move, yet your modesty is preserved. They also work as good cafe curtains in bedrooms/bathrooms, allowing plenty of light in, preserving modesty, and if you attach them to a rod, by inserting curtain holders into the punch hole side, they can be pushed open at times. Next best thing to window adhesives or window coverings.
