Twice today I was told to have a good Easter, "if I celebrate."
I'm certainly not offended, but I found the phenomenon quite interesting. In Ohio -- and especially in Defiance -- everyone assumes that you will be celebrating Easter. And 99.9% of the time, they'd be right.
Since moving to New York, I've become a lot more familiar with other religious holidays, and especially Jewish holidays. At the very least, it's good to know when they all are because that usually means a parking holiday-- no need to move the car for street sweeping!
