Bad news Sunday was the last day of my holidays. I went to the beach for two weeks. It was a sad day because it was my last day and because when I arrived home, I found at the newspaper that the school where I spend sixteen years of my life was burn to ashes. This School was closed in 1997 because it was in debt. They owed money to many people. Since then the school was abandoned. It was a british boarding school, with three big buildings, and now the main buildings has disappear. Probably, now is cheapper to buy the land, and maybe this is the reason why I burnt. Anyway, the school is gone but we, the students, will keep the memories. http://www.elcorreo.com/alava/araba/201406/29/declarado-incendio-internado-abandonado-20140629110007.html

My familiys village My father´s family are from a little village in Burgos. It has about 50 people living there. Is small city but It has a long history. Before I was born, my great-grandfather found some pots and dishes while he was digging a wine cellar.This pots and dishes were made by the visigothic, They came to the iberian peninsula in 507 and stayed until 711. This means that there was a village, at least 1200 years ago. Now you can find this pots and dishes in a museum in Burgos, It doesn't say who found them only where this was found. My father also told me that he found once a roman coin when he was a child. I´ve never seen this coin but since that day I started looking, But I never found any ancient coin, just some spanish pesetas. There was a time that I thought that this village was going to have no people living there, so end of history. But this village is in the "Camino the Santiago", and this is becoming famous. People is going back to the village, now you can find a shop, a restaurant and a place to stay if you are doing the "camino". Maybe somebody will find our dishes in a few centuries.

A visit to my godparents Today , I went to visit my godparents. They live 100 km away from my house.They are my grandmother´s younger sister and her husband. They live in a country house and the have fruit trees, they are in god shape, but they are 82 and 90 years old. So once or twice per year, we help them fruit picking. Today, only two cherry trees were ready to be ¿harvested?. I took my brother in law with me, because he is really fast picking. Together we collected 9-10 kilograms of cherries (and I ate about half a kilogram). Next week we are going back to visit them and maybe we can collect all de cherries before the birds eat them.

First writting (not a good title, sorry) I've found this web about a week ago, but iI didn´t have the courage to write anything in english until today. My english got rusty after ten years of not using it. I´ve been correcting (kind of trying) spanish writings from people from the USA, Irland, China.. and I´d realized that this is a good place to learn or practice another language but is also useful to learn how native spanish, from other parts of the world, are using our language. I am learning from them new words that I´ve never heard and new meaning to others. Does this happen with english? Is the same in english? Do you have different words in the States or in the in UK? different meanings for the same a word?
