I think that there is some trade-off between "amigo" and "close friend" barriers. For some countries (Germany, Poland, ...) the initial contact is icy, but after breaking the ice, it's easy to get straightforward to confessions, biggest dreams etc. For other (e.g. Spain, USA, ...) the initial contact is warm, but it is somehow harder to became close friends (or at least - it's hard to tell). At least for a Pole, it may work different way for different people. I am curious if it is possible to get some objective data on it (any ideas?). And, as a rare counterexamples, for me it was usually warm/easy for Italians and cold/hard for the French. Politeness is yet another layer, but not the same as warmth.
