Nowadays, if a man living in a civilized country (ha!) hears cannon blasts in his sleep, he will, of course, mistake them for thunderclaps, gun salutes on the feast day of the local patron saint, or furniture being moved by the slime-buckets living upstairs, and go right on sleeping soundly. But the ringing of the telephone, the triumphal march of the cell phone, or the doorbell, no: Those are all sounds of summons in response to which the civilzed man (ha-ha!) has no choice but to surface from the depths of slumber and answer.
But then why, when talking on the phone, did they quarrel, on average at least once every four sentences? Maybe, though the inspector, it was an effect of the distance between them becoming less and less tolerable with each passing day, since as we grow old - for every now and then one must, yes, look reality in the eye and call things by their proper names - we feel more keenly the need to have the person we love beside us.
