A symbol of how much Mark cared about this town is the restaurant right next to Aetna headquarters, sitting idle — begrimed and begging for a buyer — for years. It used to be a lively place. It was the Oasis, the Comet. When I was kid, it was kind of a swank place inside those shiny art deco walls. In those days, the place was the Aetna Diner. Sigh. It would have taken a tiny shrug of leadership on Bertolini's part to breathe life into the place.
