It's nice to think about how there are millions of people in Mexico who speak indigenous languages to one degree or another. Years ago I visited my grandfather who was in a nursing home in Mexico City, and there was a young girl working as an aide who must have been no more than 18 years old. My aunt told me that the girl barely spoke any Spanish. Noticing my immediate confusion, my aunt replied with one word I had never heard before: Zapotec.
