Good Friday?

Zoe asked why she had Friday off and because I don't participate in the Catholic traditions or go to church anymore I told her "Good Friday is a day where you get to have a day off from school, but you have to be good ALL day!" I'm not sure she bought it, but what else am I going to say "It was the day the Catholics believe a man was nailed to a cross and that is why you have the day off?" Hmmm, wait a minute, that IS what they told me....
Oh, that reminds me, I have therapy Friday!
