I have asked people to email me laughter and crying photos of themselves. After I receive enough, I will put together a book. I am calling this work in progress Emotion Aesthetic. Here is one of the responses: "I had "just" come back from traveling overseas for 3 1/2 months on a program called Semester @ Sea (thus the tan). If I recall correctly, Mom had said something really funny as my sister was getting ready to take a picture. I cracked-up and the look on her face is her giggling at herself".
