Cas, you seem quite intent on showing us all your pictures, yesterday and now today. Yes you are a pretty girl, but you also seem pretty desperate for compliments. Why carry on fishing when you can catch quite easily without opening your mouth? Good luck with your search for answers.
Oh and another thing, Jessica Simpson is also an extremely deep thinker, a very bright girl by all accounts, so you should count yourself lucky to be likened to her.
I don't think you look like Jessica Simpson particularly, mind you I don't think she's attractive, but you look alright, pleasant average girl in the street.
