Maybe it is true

if someone love you, don't try to hurt her/his heart, you should keep your heart without looking the other person.
if she or he hurt your heart. don't do the same thing that you get from her/him to other person because it is so sad.
make her or him feel comfortable beside you, make her or him feel miss you if you don't give a news.
if you and her or him must split, please keep smile and don't think to stop your life, if her or him is your destiny, you and her or him will be together on the other time. believe.
