I'm going to talk about the most beautiful and problematic topic: love.
I think love is beautiful when you are in love wuth the right person, who loves you, but if you have a crush with someone who doesn't love you is hard... it happens very often and it's sad because you can't be with that person because he loves an other girl. Maybe you've been talking with him for a long time and you need him but I always say: If you fall in love with a boy, be his friend and if he doesn't love you, you've won a friend. Sometimes love (not always) is unfair and the people who doesn't want any serious retationship has a lot of people in love with them, even if they don't deserve it. And the people who deserves love doesn't finf they "mate". Everybody is going to love someone and we must enjoy because life is too short to suffer for love and this kind of things.
