In the Bruins’ media guide, Chris Kelly  put that the one word he would use to describe himself is “grumpy.”
Now, Kelly has yet to reveal that characteristic in his dealings with the media, but on Monday, he’ll take one step toward being a grumpier old man. Monday’s tilt with the Islanders will be the 500th game of Kelly’s career.
“I didn’t know it was 500. My dad actually reminded me yesterday,” Kelly said Monday. “It’s always nice to hit a milestone like that.”
The soon-to-be 31-year-old is in his first full season with the Bruins. Acquired last February from the Senators in exchange for a second-round pick, Kelly fit in quickly with the Bruins’ tight-knit group, so well, in fact, that when Mark Recchi  retired, it was he and Andrew Ference  who inherited the ‘A.’
“He’s wearing an ‘A’ because he’s a good leader and also a very well-respected teammate,” Claude Julien  said Monday of Kelly. “He’s got a lot of qualities that when we got him, we knew about. All he did was reinforce those.”
In his career, Kelly has 80 goals and 108 assists for 188 points. He will center Benoit Pouliot and Jordan Caron Monday.
