Body language can speak volumes about a person's personality if you're adept at people-watching.
Next time you meet someone with a holier-than-thou complex, watch how they move, look around, and take up space. Things like that. There's confidence and then there's something more than confidence, the attitude that just says "you're not as good as me/I'm better than you."
Once you get good at reading body language you can spot these types of people a mile away.
It's the way that she acts around other people mostly. Clothes mean very little about the way I view her (I've grown up around various dressers - fancy and not quite so fancy). If she's acting as if she has too much going on in her life to be bothered about anyone else's life, it's a major 'stuck up' sign. Also, if she's anti-social (ie - bitchy) then she's stuck up.
My favorite is when I'm making eye contact with a girl, and she just look away at eye level. Not only that, they sort of roll their eyes or looking away with hatred in their eyes. I understand that if you're not interested in a guy, just look away. But there is a right and a wrong way to do it. I think the right way to look away is simply give the other person a slight smile. Make sure it's a "polite" smile and not the seductive/flirty one. Then you'd lower your glance(look down slightly) then look away with grace(not to fast). Those gestures send the message of "I acknowledge you/your intention, but sorry I'm not interested."
People think I'm stuck up all the time and I hate it. Some of my friends always say to me the first time I met you I thought you were a snob or a bitch. But I'm like the least stuck up person I know. And I don't think people should judge people just by the way the act or the way they look to others. You have to think..would you like people judging you when they don't even know you.
I think a girl is stuck up by the way she acts. Personality and attitude say it all! I wouldn't say its the way she dresses... but if I see a girl who I think is stuck up and she's wearing the same thing as a different girl I see.. I may think that girl is stuck up also
Did you ever know someone that was backstabbing and fake? Yet when you try to warn people about you, they see the fake performance as real and get mad at you for it? If so, then you will totally see...
When giving tough love to a friend or even someone you don't know - I would like to bring up a few points that may seem "considerate" to think about, before advising. Tough Love isn't for everybody....
