Unfortunately, I have other obligations that day so won't be attending. Is Father's Day that important to a lot of people that they'll not be able to make a meeting tomorrow? I didn't even realize that holiday was tomorrow until this announcement.
Jim — What time?
Joshua — For three decades, Father's Day never managed to meet my attentional threshold. Last Sunday, though, I got the first dozen-odd "Happy Father's Day!" salutations I'd ever received, and I must admit that I was absolutely tickled pink.
I will be at Clear Conscience Cafe at 581 Massachusetts Avenue Cambridge, MA looking for other Less Wrong people on Sunday the 27th. This breaks the previously established pattern of meeting on the third Sunday of each month, to avoid conflicting with Father's Day. As usual, I will bring my boxes and challenge anyone who comes to a puzzle. No one has answered correctly yet; come be the first!
