This was one of my favorite moments on a recent trip to Cuba. We were in the fishing town of Cojimar, just east of Havana, and I felt the need to wander off a bit. I went down an alley and met a local man with a beautiful white labrador retriever. I asked if the dog knew how to sit. He replied "Yes! Ask him." I said, "Sit." Nothing happened. The man then said, "Sit." Nothing. Then, with a giant laugh, he said, "Oh! I forgot. This dog only speaks Spanish." Brilliant.
