Synchronicity

In church today, the sermon started with Esther ch. 1 and the seldom told tale of Vashti, rebellious queen. This struck me as particularly ironic since today was the day I'd set to reread part 1 of "The Machine Stops" (which I've assigned for my writing class), wherein the main female character's name is... Vashti. There may nothing to it, but it's an interesting coincidence.
