Freebird Books and Goods has these letter writing events every now and then. I’m tempted to go this evening.

PEN TO PAPER A Brooklyn
bookstore invites visitors to break free from email at a letter-writing
session. They’ll provide the pens, paper, and envelopes. Stamps are
available for purchase on site, so no more toting around that note for
weeks until you happen by a post office. Tonight, 7-9 p.m., Freebird
Books & Goods, 123 Columbia St. at Kane Street, Brooklyn,
718-643-8484, free.
