The most disturbing silence is the silence of people you think are close to you but aren’t, at a time when you need them the most. Friends whose emotions of friendship are not as deep as you thought they were. Who were not as good a friend to you as you were to them. Who like you less than you like them. Relationships are subject to terms and conditions as much as any business transaction. And no one can determine how much a person is to be liked by another.
