Facebook... some years ago, this social network was created and it was amazing for young people, everybody liked the idea to be chating all the time and have communication with the loved ones; but this last year facebook has been changing, now it is not to popular as it was before and some people have not used it for a long time, facebook is still being a nice social network but for some reason we desagree with changes, we don´t like it any more as we do with other changes in our life... So the lesson that I received with this example is: Things are going to be changing all the time and we have to accept this because anyway we are changing too... As all the time my phrase is: "Be possitive and everything is going to be Ok"... :)
