When someone is sad, it is easy to love him, convince him to smile. Because he is lost in his own slime.
But what matters more is to be pull yourself up from your ego, after a fight which happened a while ago and make him laugh. This takes efforts. Because you have to lose something of yourself a little to win him over.
You have to keep your differences, attitude aside. You have to value both of your love more than just your love.
You have to forget whoever mistake It is. Because you have to respect the person and that feeling more.
