that time i bought some suede cord from the bead seller who had his cart at the sam the record man store. he measured out the cord picked a pocket knife up and just as he made a slice through the cord he made a panicked look at something or someone behind me as he was slipping the knife through the cord and cut his finger, a deep enough cut to drip blood.
how this could be used in a fiction. some one being followed by a gang of rogue csis agents who have escaped their oversight escorts.
this person stops to buy some cord at a jewelry sellers cart out side of the sam the record man store. as the vendor is measuring out the cord the persons eyes are caught by some movement in the reflection of a window behind the vendor (maybe it was a mirror hanging on the vendors cart) it is a person standing behind him on the corner of the sidewalk on the opposite side of the side street off of yonge. the mysterious person is motioning to the vendor and pointing to the person he is serving.
he's seen that face before and thinks "could that person be one of the rouge csis agents or one of their organized crime assets or one of their oversight escorts thinking they would find the agents they oversee if they found the person the agents were following ?". he makes a quick mental sketch of the shape of the lurkers head and face as well as where the main features are for later comparisons and turns his attention to the vendor.
when the vendor looks up and sees the person on the corner of the sidewalk make the strange gesture to him he gets a panicked look on his face, looks at the customer looks back across the street then fumbles with the penknife he is using to cut the cord so it slips and cuts the underside of his wrist.
