We respect the face of a man whom we see every day, provided he has never offended us. Neighbours can be very convenient, and they can be very troublesome, to one another. If they are good sort of people, they are naturally disposed to agree. We expect their good agreement; and to be a bad neighbour is a very bad character.

Context

“The Romans expressed this sort of attachment by the word necessitudo, which, from the etymology, seems to denote that it was imposed by the necessity of the situation. 4 Even the trifling circumstance of living in the same neighbourhood, has some effect of the same kind. We respect the face of a man whom we see every day, provided he has never offended us. Neighbours can be very convenient, and they can be very troublesome, to one another. If they are good sort of people, they are naturally disposed to agree. We expect their good agreement; and to be a bad neighbour is a very bad character. There are certain small good offices, accordingly, which are universally allowed to be due to a neighbour in preference to any other person who has no such connection. This natural disposition to accommodate and to assimilate, as much as we can, our own sentiments, principles, and feelings, to those which we see fixed and rooted in the persons whom we are obliged to live and converse a great deal with, is the cause of the contagious effects of both good and bad company.” source
