All faces look the same

I find it immensely frustrating that people expect me to tell people apart by their faces, instead of by their hair, their clothing, their height, and other things which do not look the same. I find it puzzling that people consider the inability to distinguish faces, and the inability to reliably guess someone's feelings from their expressions, to be disabilities. Why don't they consider the inability to levitate R2 units with their minds a disability? The former two are just about as far from plausibility as the latter.

Anyway, BoingBoing has a thing on this.
