your cousin is just being totally classless. you dont do that to family members - especially when you said your sister and her were thisclose growing up.... that means you were at least SOMEWHAT close with her .... she is just being childish using the "you people" excuse. you are exactly that - PEOPLE. there is no need for her snotty remarks. in my eyes - you dont need to go to her wedding, because you'd just be overpaying for a dinner that you and your family could go out and have some where else -- and without the hassle !!
