  438. <p>Je repense à Montréal et ses allées, lieu de rencontre, de racolage et de voyeurisme aussi, parfois.</p>
  439. <p>Je me souviens de cette légende qui veut ce les escaliers en colimaçon à l’extérieur des maisons, somme toute une bien mauvaise idée dans un pays ou l’hiver est roi, auraient été imposés par une église catholique soucieuse d’éviter toute promiscuité dans la relative chaleur des cages d’escaliers intérieures, préférant pour sauver les bonnes mœurs garder au grand jour les croisements de paroissiens.</p>
