I will be in Medellin this summer and want to know what advice you have for relating well to the people who live there. By many accounts they tend to be welcoming and friendly to visitors, and in the one weekend I spent there a couple of years ago that seemed to be true. I will be going back now to spend a couple of weeks there and have a more in depth experience of the city and people.
I have travelled to Mexico and Ecuador and have a conversant level of fluency in Spanish (I hold a DELE) and thus am familiar with Latin American culture. Nevertheless, each country and city is different and I want to know that specific advice you have about this city. I really don't want to be perceived as an ugly american, a #@%$ gringo, or God forbid another sex tourist (apparently there is a lot of that in Colombia and recent events in Cartagena won't help).
What is it that paisas would most appreciate if visitors were to do it in Colombia?
I apologize if this seems like a dumb question, and I know the answer is not going to be formulaic, but any observations you have made in your own experiences there would be most appreciated.
