The other week I found myself walking behind a professor before class. We were passing a hedge the grew along a sidewalk. Some kind of evergreen thing with nubby fingers growing in all directions instead of leaves. Occasionally his extended hand would brush or reach to fondle the hedge's green fingers and a little plume of smoke would form. I don't know if the hedge was just dusty and he was disturbing it, or if he was a fiery demon, but every day since that I've passed the hedge, I've been clutching at it and shaking it and trying to make the smoke come out, but it hasn't.
