Yesterday, biking home from the gym and library, I noticed a cloud or two, small, white and fluffy, on the horizon, but mostly the sky was sky blue. And I thought how nice it would be--for a few months--to be in Paris, which we will on Wednesday, and to look out our kitchen window every morning and see a grand show of clouds, changing, like the ocean changes, and silver-grey as if the zinc roofs of the buildings around us ran off into the sky.
