dont like them

Hi I was wondering about family. What if your family isn't really close?. What if you can't stand them?. I have this with someone related to me through marriage. I can't stand them even though they have been 'family' since I was a teenager. I don't like them and I could write you a list of how evil they are and self centred. You know one of these people who want everything now and they don't care if they get into debt if they get it. They get their partner to pay and work their bollicks off just so their bitch can have some shoes they saw in a shop.and it would be cool if they where nice looking but they aren't, they are just normal looking. So I'm pissed at the world really that a person can be crap and use everyone and like to get drunk. And they seem to have everything .and others don't. How do you tell someone you don't like them?. Will they have guessed by now through the ignorence I've been giving them for years????. Am I rude?. Am I bad?. Or is bad telling them to their face and leaving presents of dog poo in their Xmas pressies. Present I don't want to give them cos they take stuff back!!. Anyway, I can't be bothered. Really hate this person they are smug too :(
