Roots

The town where i live is surrounded by suburbs that used to be villages. There's always a handful of old streets, with the traditional houses who don't like anything special, identical in all the villages, a small square or two with a few orange trees, and then row after row of new houses à la American Beauty in the places where the olive trees used to grow. For anyone living in a 30 kilometers (that's 20 miles) radius of Sevilla, the only difference between these villages turned neighbourhoods is how distant from town, or how well communicated, they are. They is absolutely nothing special, unique, even interesting about any of these villages.

Not for the locals, the people from the old houses.  The other day I went to the bank, and in the long queue I heard a few women chatting. The conversation started with one of them saying that locals who had moved to villages A, B and C a long time ago had just moved back to ours, and everyone agreed iin that they had been stupid to leave the village in the first place. They were talking about places that were two to ten kilometers away in the exact same tone that most people I know would say "La Guiri spent a year in the USA, and she just came back. Good for her, I can't understand why she went so far away in the first place". the conversation revolved around the same subject for twenty minutes: not about the advantages of our village, but about the perfect foolness of anyone who moved to a different place. It reminded me of a conversation I overhead a long time ago, also in my village.

-... and then Juan came to live here, because originally he is from Village B.
-Village B!? Why on earth did he come to live here then? 
-Because he married his girlfriend, and she was from our town.
-Ah, OK then.

It seemed to these people that the only reason why anyone would want to live more than two blocks away from their birthplace is to marry someone who lives a little bit (not too much) farther away.

What is it that makes people love home so much?
