Always

It's always necessary know when a stage ends. If we insist on staying more than necessary, we'll lose the happiness and others stages that we need to live. End cycles, close doors, end chapters... It doesn't matter the name that we giver to it, what matters is live in the past the best moments of our lifes. It hurts say goodbye to a friend? It hurts end a relationship? Did you left you parents' house? Went to another country alone? A long friendship ended suddenly, without explanations? You can pass a lot of your time asking yourself why all this happened. You can tell yourself that you'll never give another step while you don't understand the reasons that take some things to happen, the things that was so important and solid in your life be suddenly turned into dust. But this behavior will be a wear and tear to everybody: your parents, your friends, your brothers... everybody will be ending chapters, turning the page, moving on, and they will suffer to see that you are in the same place.

PS: Sorry about my english, everyone :B
