Dun judge a book by it's cover .

When a person shows her sad feelings out , It's obvious that she needs people's attention as well as care & concern .

When a person looks happy in the outer side but sad in the inner side , tell us that she does not need any people to questions about her situation and needs no sympathy/attention/care from others .

So when you all see people who seems to be very happy ,

Don't assume that she's really happy .

I will forget you & move on .

I still can lead a happy life without you.
