This photograph (given to me by a friend) was found inside a Carleton University library book. On the back of the photograph is the following text:

Melanie and Jeff (Stain)
January 1991

Why do you suppose Jeff's nickname is "Stain"? More importantly, are these people genuinely happy to be photographed together in the bath? Or are they only smiling in that "I am going to kill you" sort of way?
