Small towns in Spain are a different world sometimes. I have been to a few very small ones, and you can feel the taste of an old Spain that no longer exist out of those places. Family is everything, and the parents still tell their children how they should live their lives and everything. What I'm saying here, of course, are my personal impressions.
Bear in mind that bigger villages are nearly like cities, and they live in the 21th century, with all the Play Stations and the gadgets, and following the MTV (or whatever). There are villages in Spain bigger than small cities and towns, so the name doens't mean a lot. If the place is big enough, or close or well connected to a reasonably big place, it is not that different from the rest of the cities. Of course, much bigger cities are more stressful and hectic.
But I am talking small villages. I have witnessed how the family of someone I know imposed some sort of mourning to everyone in it, because one of the grandmothers died, so women should dress in black at all times, and no one should laugh for a whole year. Yes, I mean it. I tried not to be disrespectful, but I found it hard to contain my laugh sometimes; everyone pretending to be so serious...
I don't know what is like in small towns in the States, but in Spain they all know each other, there are no secrets, they normally go to church a lot more than in big cities, and they eat a lot of what they produce in the area, rather than going to bigger supermarkets. They still make themselves things that no one else would even know where they come from or how they are made (e.g. chorizo), and they have a stronger sense of community. Men go to bars where few women go to (specially alone), and older men like to play cards, domino and chess. To me, it is a bit boring, though.
