On the first day of Sukkos, there was a knock at the door. I opened it to find a group of children thrusting a bag in front of me. "We're Sukkah-hopping!" they announced. I was rather taken aback. It occurred to me that my shock might be because I am English; I am likewise a little disturbed at the custom of Christmas Chanukah presents, which would have been way too Christian to do when I grew up in England. But my American wife was likewise surprised at the kids who showed up begging for candy. "Is it Halloween?" she asked me.
