Josh is non-descript in my perception: a mere mirror of his father. He seems so one-dimensional that his only purpose is for incidental dramatic effect.

What's so sad is that while this is true to a word in a literary sense, it's also true in a real sense. His character is based on real people I've encountered, people who seem just as one-dimensional in real life because they only present one side of themselves for the world, and it's seldom a flattering one. Does anyone else know people like that?
