One afternoon in early September 1999, shortly after we moved back into Kohl Hall for our third year as roommates, Amy and I discovered this interloper living just outside our window. We named her Lachesis, after one of the Fates (Clotho, the weaver; Lachesis, who measured the cloth; and Atropos, who cut the thread — rightfully, she should have been Clotho, but Lachesis just sounded cooler).

We and Lachesis lived in harmony for at least a week, until one morning she and her web had vanished. Amy and I maintain that she must have been power-washed off of our windowsill.
