you see a hand writing out the name Shannon in blue ink on a pad of adhesive-backed, pink paper in the middle of a big, poorly-proportioned cartoon heart, also in blue ink. the camera pans up to see a smirk on the penman's face and follows his hand as he plants it on the wall of the building he is walking by. the camera revolves around to show that this is not the first note he has left in his wake, and other people start coming into frame showing that they too are leaving similarly culpable notes in their wakes. as the scene progresses the notes become more densely packed on buildings, telephone poles, mailboxes, store windows, etc., each note a different, vivid, day-glo color. finally, a bus is seen rounding the corner completely covered in the damn things and the effect of the multi-colored, fluttering notes looks like a bird's feathers ruffling along the aluminum hull. after following the bus for a few seconds the scene is abruptly cut.

is this :
a) a commercial for post-it notes?
b) a chilling, cautionary glimpse of young sobriety?
