We walked to "Leather Street" (leather is an artisanal industry in Cotacachi, and I purchased a nice leather jacket here for a good price on our prior visit). In between leather goods shops was a small dentist's office. We went inside and waited in a narrow hallway. There were several posters in the hallway for dental hygeine, including one which would NEVER fly in a dentist office in the USA. It depicted a small rat wearing a necktie perched on a pile of teeth. There were three crates next to him labeled "Perez & Perez: (in Spanish) children's teeth." When I told Craig this, he remembered that this is a tooth fairy-like tradition in Spain and Latin America. Perez, the Tooth Mouse, collects children's teeth from under their pillows. Nonetheless, it seemed creepy and not what I would expect to see in a dentist's office! Not to say that the Tooth Fairy makes much more sense, but at least it's more pleasant than a rat burowing under your pillow while you sleep!
