Shavuot, which starts tonight, is all about learning. Jews are supposed to stay up all night reading in celebration of God giving Jews the Torah. What makes the holiday rare, though, isn't the reading part--what Jewish holiday doesn't involve that? It's that there's no bad guys in the story. Unlike Passover, we don't commemorate Jews escaping a pharaoh in Egypt, or, as in Hanukkah, a revolt against the Romans. No matzah, no latkes, just books and books and books.
