Dear heart, I lit an aromatherapy candle from last Christmas, thinking to release the smell of late summer flowers, of roses and champagne; but all it did was give the room a slight top note of funeral parlor. I waited to see what the middle and base would be, then the unique chemical heart of the drydown. There was only a smoky signature reminiscent of the moment after the child blows out all the birthday candles. Fragrance needs a body to define it, after all: a chemistry against which to blend the oils of an accord. Sillage is what trails beyond our passage, changing intensity from our heat, our cold; whether we sit on benches in the sun or walk through drafty corridors resembling catacombs.
