Steam

As I left the house this morning, I saw a strange thing.  I saw steam rising up from the roof of two houses across the street from me.  Nowhere else.  Now, I remember enough about high school chemistry to know steam is water in gaseous form; it is normal on hot afternoons after a rain for steam to come up from the asphalt as the heat of the surface essentially boils the water that hits it.  But this was morning time — warm, but not unbearably hot.  And it was just the two houses, as far as I could tell.  (I’m virtually certain the houses were not on fire, in case you were wondering.  The thought did cross my mind, though.)
