Yes she is

She's beautiful.  

She does not know it. 

Never in her life was she told she's beautiful.  

Every woman must hear it even for once. 

No no

She heard it before. 

You're beautiful someone told her. 

It was music to her ears. 

It was music but out of tune when she saw the face of the one who told her this.  

His face full of sarcasm. 

Since then 

She never believed on anyone who praise her and tells her she's beautiful. 

You're beautiful 

Is one of the most awaited phrase and most appreciated phrase every woman loves. 

Not her.  

It's an insult to her.  

She's not beautiful she know.

She knew ever since she's little 

The problem is,  everyone wants to hurt her with this phrase.  

The phrase that should be comforting is hurting her. 

She's not ugly

She's beautiful

only those who know her, know how much. 

She's beautiful 

She just doesn't want to accept it anymore because of everyone who made her feel she's not.
