On Monday, April 8, I’ll be giving This Chair Rocks in the Cooper Union’s gorgeous new building on the East side of Third Avenue and East 7th. 6:30-8:30. The Rose Auditorium seats 200, so bring a friend. Ideally a friend who’s more than 15 years older or younger than you (starting at age 16; no bonus for babies). Door prize for pair with the biggest age difference.
