Between spoonfuls of cereal, I was visited by a quote from Rivka Galchen's odd and fascinating novel, Atmospheric Disturbances:
"We get these wrong feelings sometimes,
feelings like articles slipped into our luggage
but not properly ours. I think of it like vestigial
DNA. Code for nothing, or for the wrong thing,
or for proteins that don't fold up properly and
that may eventually wreak great destruction."
