After the Bruins’ emotional game Wednesday — a shoot-out loss to the Sabres, unfortunately — Tyler Seguin and his teammates hung around to say hello to some of the police, fire, and emergency personnel (left) who were the first responders after the Marathon bombings. . . . First responders were also hailed at Timeflies’ sold-out show Thursday at the House of Blues. Timeflies are Cal Shapiro and Rob Resnick, both Tufts grads.
