The Face..

..in the shadow of the smoke is the face she dreams at night and wonders about. It provokes the sensation of deja-vu she has when she drinks her morning coffee. It's the cause of which she crosses the street with eyes wide shut and cars go round her blowing their horns out. It appears again in the smoke of the cigarette she has when she's out with some friends later in the evening.

..after days of torment and lamentation, the answer springs out of Nowhere. The Face is hers.
