“Relationships I thought were going to last didn’t last. And to tell you the truth, the past five years, the older I get the shorter the relationships get, and now it’s like a game of musical chairs. There’s nobody left. It’s sad.” — Unmarried psychologist Dave Mahony, 42, speaking to N.Y. Times writer Allen Salkin in a piece about middle-aged guys (some nudging 50) living in Fire Island house shares and cruising chicks and sipping Heineken from plastic cups at crowded parties. Mahony’s observation is poignant and well-sculpted, like something John Guare might have written for a play about older guys whose string has run out.
