My longtime buddy, Stuart Klein, passed away Sunday, and I have to say, I’m going to miss visiting with the guy who probably framed more diplomas, family photos, at the gallery he and his wife, Sylvia, owned and operated for so many years on Main Street just south of the old library – S. Klein Gallery. I first met Stuart back in the ‘80s, and you know how I could tell the guy had a soft heart? At the time, The Advance had an ad salesman whose only problem was, he couldn’t sell ads. He was sort of a sad sack,
