If you don't get it, neither did I at first. All I knew was that my daughter informed me as we were heading out the door for church last night that the next day was Pie day, and if she brought a pie to her math teacher she would receive extra credit. So at nine o'clock last night I started making pies. Fortunately, I had everthing on hand. It wasn't until my husband came home that he enlightened me on "Pie Day." Today, at that time-tomorrow, is March 14 i.e. 3.14...pi...Oh....I get it!
