The Joys of Tu B'Shvat
There is a little bit of a pagan flavor to it - the anthropomorphosized trees celebrating their New Year, but that doesn't bother me. I enjoy going to the store and shopping for weird exotic fruits to put on the table. Last year it was prickly cactus pears, and today it is Asian pears.
There is a whole Kabbalistic tradition of the Tu B'Shvat seder, but that is a little too much for my non-mystical household. Instead, we just enjoy the day in a very simple way.
