Some moments make us measure the worth of our lives. Hence, our tendency to avoid.
We are seldom alone. We strive in fact never to be so. Something about it gouges and creates a gulf where none exists. Even so, we feel it deeply when it descends, especially when it prolongs. Hence, the value of friends. By these we are saved from ourselves. Those without are prone to endure without complaining (or pretending), as many of these require. Even when befriended they refuse to be severed from themselves.
