A man and a woman fall in love and find happiness. Another man and woman fall in love, and don’t. It’s a setup used countless times, but we still find the patience to hear it again. What we don’t often find, however, is the process of writing the love story, stuck in the middle of it all. That improbable twist brings Will Eno’s The Flu Season into the tradition of art looking at itself, a self-conscious exercise that baffles some, but is a peculiar delight for others. With Eno, called “a Samuel Beckett for the Jon Stewart generation,” by The New York Times, it’s the humor he pulls from this double-vision that makes the play a haunting look at human desire, rather than a mere display of technique. Directed by Aaron Aguilar, The Flu Season received the 2004 Oppenheimer Award for best New York debut by an American playwright. $10-$25, 8pm Thu-Sat, The Overtime Theater, 1203 Camden, (210) 807-8646, proxytheatre.org.
