WILLIAMSTOWN, Mass. -- We were left wistful at Tuesday’s town meeting not to be able to greet and hear the cheerful curmudgeon of Williamstown – Dagmar E. Bubriski. She died last week, at age 84, and a progressive illness had taken her away from the civic life she loved. You can read the details in the obituary her family wrote. A memorial service and some other events are tentatively set for Aug. 3. With Burbriski’s passing, I hope as a town we’ll also reflect on the value of the responsible critic in society, the voice we don’t always want to, or have time, to hear, and the value of that in stitching a community fabric that is open, tolerant and affirming of many views.
