Turns out there is a 3/14 that comes every year. And on this day, nerds of the world unite in the eating of pie. That delicious, wonderful dessert.
So on pie day of this year, I went to Village Inn and bought my favorite, strawberry rhubarb. And then I took it home, and started eating it from the middle. That's not something that you get to do very often. Its fun. I highly recommend it!
