Bye Bye Babies. Human offspring are completely immobile. Normal people who are immobile are given choice parking, special equipment, and exclusive public transportation.

Human nature, upon meeting someone who cannot speak the language is to speak louder. We don't know why, it just sort of happens. When that ultimately doesn't work, we start with the hand gestures.
