Do not only be close with someone who makes you happy. Be close with someone who cannot be happy without you. It makes a lot difference to him at least.
Happiness is like a radio station, broadcasting all the time. you just have to learn how to tune in and receive it properly. Stay tuned and be happy always!
A gun can kill, fire can burn, wind can chill and the mind can learn, anger can rage till it tears you apart but the power of your smile can heal a frozen heart.
