I recently had the opportunity to see a couple of great plays in New York. One is Our Mother's Brief Affair by Richard Greenberg. Rich was my roommate at Princeton many years ago and has gone on to become a highly successful playwright. You can read a review of his new play here.
The other play I saw is Fun Home, an autobiographical musical about a woman coming to grips with her sexual orientation and with her father, a closeted gay man who never fully came to grips with his own sexual orientation. It is based on the graphic memoir of the same title.
I highly recommend both.
