How Many?

I started my Christmas shopping last night! Am I on the ball or what?

Let's see, today's the 19th...Christmas is on the 25th...19 from 25 is 6...I work 4 of the next 6 days...4 from 6 is 2...but we can't count on stores being open on Christmas eve...that leaves 1. One day.

I'm in trouble.
