Perception

Once there was this guy who was in love with a girl. She wasn't the most beautiful and gorgeous but for him, she was everything.
He used to dream about her, about spending the rest of his life with her.
His friends told him, "Why do you dream so much about here, when you don't even know if she loves you or not? First tell her your
feelings, and get to know if she likes you or not". He felt that was the right way. The girl knew from the beginning that this guy loved her.
One day when he proposed, she rejected him.

His friends thought he would take to alcohol, drugs etc. and ruin his life. To their surprise, he was not depressed. When they asked
him how was it that he was not sad, he replied, "Why should I feed bad? I lost one who never loved me and she lost the one who really loved
and cared.
"When life give you a 100 reason to cry, show life that you have 1000 reason to smile."
"Life is wonderful if you know how to live."
