Living with two cats on a houseboat teaches me many things. They love their routines - when they eat, when they sleep, a lot, where they sleep on the houseboat at certain times - one by the heater, one on the couch, one on Phyllis’ head at night, one curled up against my back. There is rhythm to routine - comfort, ease, flow. And this is true of me as well, when i am in my groove -writing and reading and exercising and teaching and editing and sharing coffee with Phyllis in the morning as we practice a new nautical knot or read a piece from the tao de ching. And I know, and the cats know that the difference between a groove and a rut is only two inches, the difference being that the cats never bother to measure. No need to calculate when you just know.
