Though I normally find statements like the one I'm about to make annoying and overblown, in this case I find it entirely appropriate: if you haven't had arepas, you haven't really tried Colombian food.

For various reasons, historical (see: United Fruit Company, CIA involvement in Latin America) and practical (hold up during long shipments, ripen after being picked), bananas are one of the most common fruits in the United States and Europe even though they are grown far, far away. Plantains, on the other hand, are rarely seen. Before living in Colombia, my interactions with them were pretty much limited to the sweet plantains that come alongside the moros y cristianos (black beans and rice) served in Cuban restaurants, and as much as I may have enjoyed them, I never gave them too much thought.

La Galeria in Cali is exactly the kind of market I like: friendly produce and herb vendors, unfussy stalls selling fresh juices and rellena (blood sausage made with rice, peas and spices)...

"Vea, se le cayo esto" - Look, you dropped this.

If you are one of those people who unwraps a candy bar and lets the wrapper drop to the street (and if you are, what is wrong with you??), and if you happen to be in Colombia while you do this, it is quite likely that someone will (ever so politely) tap you on the shoulder to hand you your wrapper, saying, "vea, se le cayo". Then they will smile (with only the slightest hint of passive-aggresiveness), and be on their merry way.
