Our reading
An editorial interpretation.
Andrew treats strangeness as universal and makes concealment the real difference between people. A polished appearance therefore need not mean that someone is fundamentally more ordinary. The statement reduces the distance between those who seem unusual and those whose unusual qualities are less visible.
