The man looks confused. Then intrigued. Then he is walking
out of the alley, with you at his side. You’ve made it out, the circles of
conversational feedback have ceased.
It looks a bit darker out on the street. No sooner are you
by the roadside than the man has seen someone he knows, is waving at them and
walking away, completely oblivious to you or the past 10 minutes (or was it
more?).
