"My definition of friendship varies with the friend, but certain traits are mandatory. Friends can occupy the same room without robbing the space of solitude. They appreciate the difference between conversation and pointless noise. They don't snipe and bitch about other friends. They do their share of mundane tasks without prompting. They seldom whine, are secure in their own purpose and don't anchor themselves to an energy-sapping cloud of defeat."
Doc Ford from Randy Wayne White's Dead Silence.
Mr. White is a new author I've discovered. I just finished Dead Silence and found it gripping. If you like a good thriller give it a go.
