Facebook, among other social networks, has become an increasingly popular tool for people to show themselves to others all over the world. But most importantly we can dig into our friend´s lives, their friends and the friends of their friends as well. With Facebook, we can look for a distant cousin, a friend from primary education, tall people, short people, young, old… just about any kind of person you can think of, and encounter some others which were not meant to find. However, what we weren´t aware of, is which of our friends actually deleted us from their friend list.
