If you took all of the Missed Connections ever posted on Craigslist (except for the pervy ones and the ones that start with "I was taking a shit behind the dumpster when you came out the back door of the Arbys") and poured all of the tragic longing, and all of the searching loneliness into one short story, you'd have this ad. It's the Missed Connection of a lifetime. (Pasted below, in case it gets taken off CL by one of those horrible "flag" people.)
