The Kaleidoscopic Smell on Number Six Train 六號地下鐵的氣味萬花筒

The late morning ride, on number Six train in Manhattan, is often in silence; except for the occasional chatter amongst a few riders. In a rainy day, when the air smells of wet, I like grouping passengers into olfactory categories; there are the incense, the floral, the citrus, the vanilla, the patchouli, the sandalwood, the aqua, and occasionally, the homeless.
