Tax day. It might help to kick the cat. If you have a cat.
Seriously, though, when payday and tax day fall on the same day, it's hard to be as bitter as you could be. The little accountant on my shoulder (no, I don't listen too often) releases his breath. Phew. I don't think he really believes in the money fairy until he sees the paystub.
Hm...now I have to wonder what sits on the other shoulder.
