People often need to describe things quickly and so they use a shorthand. The problem is that after they use a label, they begin to think only in terms of the label instead of the totality of the experience a novel provides.
I tend to think that we are all pretty much alike. We all feel despair. We all have problems with relationships. We all become afraid. We all look at others and think these other people are more fortunate than us. Certainly the details of our life are unique. Spending time thinking of how I am different from someone else, however, does not tend to be very productive.
