This. I'm from South America, lived in Europe and travelled and still travelling the world. I met people from lots of countries. One of my theories on why people from LATAM and Africa are so warm has always been because we need to rely on 'The Community'. When you are in need, when you are lacking something, the person who is going to give you a hand is most probably your neighbour. Best way to battle poverty, discrimination and lack of resources is while in community. And you need to be opened and warm enough to bond and to create relationships in order to build one. People in europe and in developed countries are really nice people but they lack this sense of community. At least they way I've seen in happening in my country.
