The Tuesday after Thanksgiving has been adopted as Giving Tuesday. The idea is to encourage philanthropy for survivors of the consumption bacchanal of Black Friday and Cyber Monday. Today, I joined in Giving Tuesday not through more philanthropy, but by making calls for the Brattle Film Foundation to encourage donors to continue their support. Many people are “end of year” givers, meaning that December is when they make their donations for their year. That’s why reaching out to them now is so important.
