This document discusses some common mistakes that an English speaker named Harry is making while learning Spanish in Colombia. The main mistake is assuming that Spanish words only have one meaning. As an example, when Harry asked a taxi driver if there was room in the trunk, and the driver replied that there was only a "gato" in the trunk, Harry thought he meant a cat. However, "gato" can also mean "jack" in Spanish. So the driver was referring to a car jack, not an animal. Future articles will discuss more mistakes to avoid when learning Spanish.
