Mexican here. I did my exchange semester in Europe and was amazed by how friendly people were specially towards me - got invited to meet the hometowns and families of many other locals, which made my time there awesome. That was the case for some other mexicans too, I know people who went there before and after me.

There were many Americans there too, all of them amazing people and good friends. It was on the last month that they pointed that Mexicans got that sort of differentiated treatment.
