What is the effect on the reader in sonnet 130?

the effect that is givern is sorryfull for the mistress as she is compared to many of natures natural beautys as an outsider to beauty. the effect over all makes you feel sorry for the mistress but makes you want to read deeper to find more information of why maybe the poet is comparing natures beauty to something so lonely. when you have read futher you will then have a diffrent effect feeling which made me think about why the mistress may be treated horrible. the poet has been portrayed by the mistress because she lied about alot of things and about who she is.
