My wife commented to me yesterday that she thinks we celebrate well. Not necessarily in the grand Christmas-anniversaries-and-birthdays sense—or at least not strictly in that sense, because we are pretty good at that. She was talking about the ways we mark smaller occasions: the first day of summer, say, or May the Fourth, or even a Friday evening after a difficult week.

We’ve not historically done too much for Pi Day, which comes every year on March 14 (3.14, yeah?), but this year was a big one, in terms of Pi Days, given that the month, date, year, and exact time for one second could be listed out as 3/14/15 9:26:53. Twice.

I secretly ordered my wife a T-shirt featuring a drawing of a cherry pie with the symbol for pi cut into the crust, and I gave it to her that morning.

For dinner, she baked a shepherd’s pie, followed by chocolate pie for dessert. We grown-ups had Irish cream whipped cream to put on our slices, and I invented a cocktail out of apple pie moonshine, bourbon/rye (I made one of each), and Izze sparkling apple juice.

I also talked a bit about circles and circumferences with the girls, so we did more than just blindly celebrate a day without honoring its roots. I believe that we should keep the Pi in Pi Day. As tasty as pie is, math is the reason for the season.
