“Tradition,” bellows Tevye like a summer thunderstorm in “Fiddler on the Roof.” “Tradition!” It’s been stuck in my head since I saw my sister Lauren’s high school production of it last month. She played Golde, and I must say she was quite good. Well, that is if you can get past this blonde teenage, very-American girl playing a Russian Jewish mother of five in turn-of-last-century peasant garb and heavy accent. Excuse me, but didn’t I just see you on a smart phone texting a friend? How peasant is that?!? Anyway, that song’s been bouncing around in my head ever since, which is maybe why Tevye called me the other day, his voice disguised as my mother’s.
