I have a friend who celebrated the pi birthday for each of his 4 kids, so I can understand this. In theory, that is, I actually have no idea how he figured out when to celebrate.
I hope your hubby had his pie Pi-ping hot with Pi-les of whipped cream.
By the way, I think we all kind of slow down this time of year. Let's face it, the schools are probably planning their field trips right now. It was such a lovely day, who wants to be inside on the first warm days after the winter? Especially when our weatherman is using the "s" word for Friday! (No! No more snow!)
Peace and Laughter,
