The bodyguard thing has always baffled me. Do you think the other "stars" arrived with security? I have had a couple brushes with fame...Sarah Gilbert, Reese Witherspoon, Rick Springfield, Bruce Hornsby; none of them had bodyguards with them. If people feel so negatively passionate about you that you fear for your safety, that may be a signal something's a bit off.
Then again, historically it is the fans who have taken celebrities' lives...not the ones who dislike them or their persona. Frightening.
Kate probably doesn't appear happy because she is wantful, entitled and never satisfied. That makes anyone unfulfilled. It seems like she is waiting for other people to fulfill her. DWTS is not going to do it for her either.
Her social skills (lack of) are the strangest thing about her imo. There is no graciousness. She doesn't even use "please" and "thank you" regularly. She can't give nor take a compliment. She certainly can't take any constructive criticism. I'll stop now.
I completely agree with you, she has no social graces. If you watch Jon and Kate closely, anytime she meets someone or they do something nice or say something nice she is like oh whatever. She is IMHO rude and stand offish. She can't say she is shy, we all know that she isn't that.
She is to me the epitome of the definition entitled and rude ,selfish and narcissism. And now I will stop.

Her eyes were rolling at the judges comments and she looked totally put out.

I find it weird.

She didn't have ANYONE left but her bodyguard who gets payed to be with her?
). My DH on the other hand is a chatter box and I just don't understand how he can talk to people about anything and everything. For me I think part of it is growing up and not wanting people to know (kids at school) how I was living at home (abusive situation, just bad all around) so I was quiet and kept to myself and I've never "learned" the skill of just chatting with people. Even Disney - I have a hard time talking about stuff I think I know a lot about. I'm worried I'll get something wrong or the person will think I'm a "know it all" so I just keep quiet. So I guess that makes me entitled, rude, selfish and narcissictic.
