We just don't do whole things anymore. We don't read complete books — just excerpts. We don't listen to whole CDs — just samplings. We don't sit through whole baseball games — just a few innings. Don't even write whole sentences. Or read whole stories like this one.
Maybe some people. I seriously doubt if it's all or most. Somerset Maugham says somewhere that a good reader is also a skillful skipper. Reading is an art. Those who are skillful practitioners of that art learn to distinguish between what they want to devote their attention to and what they just want to peruse.
