The blind man and his wife will also have to search and scratch in their memory when the occasion arises, now they had memorised the four corners, not of the house where they live, which has many more, but of their street, the four street corners which will serve them as cardinal points, the blind are not interested where east and west lie, or north or south, all they want is that their groping hands tell them that they are on the right road, formerly, when they were still few, they used to carry white sticks, the sound of the continuous taps on the ground and the walls was a sort of code which allowed them to identify and recognise their route, but today, since everybody is blind, a white stick, in the middle of the general clamour, is less than helpful, quite apart from the fact that, immersed in his own whiteness, the blind man may come to doubt whether he is actually carrying anything in his hand. Dogs, as everyone knows, have, in addition to what we call instinct, other means of orientation, it is certain that because of their shortsightedness they do not rely much on their sight, however, since their nose is well ahead of their eyes, they always get to where they want, in this case, just to be sure, the dog of tears lifted its leg to the four corners of the wind, the breeze will take on the task of guiding it home if it were to get lost one day. As they went along the doctor's wife looked up and down the streets in search of food shops where she could build up their much reduced larder. The looting had not been complete because in old-fashioned groceries there were still some beans or some chick peas in the storerooms, they are dried pulses which take a long time to cook, one thing is water, another thing is fuel, therefore they are not much appreciated these days. The doctor's wife was not particularly keen on the tendency of proverbs to preach, nevertheless something of this ancient lore must have remained in her memory, the proof being that she filled two of the bags they had brought with beans and chick peas, Keep what is of no use at the moment, and later you will find what you need, one of her grandmothers had told her, the water in which you soak them will also serve to cook them, and whatever remains from the cooking will cease to be water, but will have become broth. It is not only in nature that from time to time not everything is lost and something is gained.
