Sometimes the best way to take a look at humans and their foibles is from an inhuman point of view. Stories wholly or partly in the alien POV both take us deeper into the alien mindset and make us work harder to understand, because no one sits around thinking all the explanations for all the ordinary things in their lives.

The first of these is probably Flatland, where the protagonist is a two-dimensional polygonal creature who has the alarming experience of dealing with three-dimensional creatures — and even fourth dimensional.
