I am in Romania and my parents are in Spain but thanks to social nerworks we can see each other every day. When my father did his military service, my grandmother could see him once every six months.
We are living a revolution in communication. Now it doesn´t matter if you live in Canada or China, you can know what is happening where you were brought up. Social networks make you feel close to a person that you hardly see. Social networks also worry about us. They tell us if it will rain where we are, they feel happy because I have new friends on facebook, to whom I never talk, they know where we are.
What I want to tell you is enjoy your privacy, your memories, don´t spend time on social networks when you can talk face to face with your neighbor or it is best excuse to go to Canada or China. Facebook does not need to know where, when or with whom you are. When you write something, the people who will read it can misunderstand your words and then you will be in trouble.
