Starting them is not so; but the art of maintaining good relationships is extremely difficult. In truth, although there are obviously different levels, it takes almost nothing for them to develop. A little goodwill, a little courtesy, and they happen. Maintaining them at this healthy level, however, requires wisdom; especially with those that seem most promising, most authentic, and most beneficial. Distance destroys them, and so does closeness. Without balance, vulgarity enters the picture; and then the worst can no longer be avoided. Better to watch them wither away through absence, preserving their memory, than to witness the misery of their deterioration!
