Thermal Noise

Laura has a genius for coincidence. When her address book fell out of her pocket and into the ocean a few years ago, we lost contact. I never know how to reach her because she's in Hawaii or China or somewhere. One day, in Katmandu, Laura bumped into Dona (an ex-girlfriend of mine with whom I'd lost contact years ago) and Dona gave her my address. When Laura told me about this, I was perplexed about how Dona had my address. Laura said that Dona had encountered Anita (Ex-girlfriend and ex-band-member) in California and got it from her.
