The project began with words, not images. Aaronson pored over personals found on the popular online classifieds site craigslist.org, which don't show their poster's picture, and chose the most intriguing entreaties. The intense fellow shown here, for example, began his ad this way: "Clingy, emotional, and co-dependent? Where do I sign up?" Aaronson then e-mailed these ads' authors to ask if he could photograph them, sight unseen. Most men turned him down, suspecting he was scamming them. Most women said yes.
