Don’t put the sadness on your face because you never know that there is someone who feels happy by your smile.
The one who gives you happiness that you can not explain will always be a reason of your sadness that you can not explain.
You can choose to feel sad of what you lose in your life or happy of what you have.
Sometimes you choose to look happy because you do not want to explain why you are sad to them who even can not understand.
Nobody is very tough in this life. Everybody feels the sadness but they sometimes pretend to smile.
