People who appear bright, talented and charismatic on the surface but  once they’ve won you over as a friend, drain your emotional energy have  been termed as “emotional vampires” by a clinical psychologist.
Not a blood relationship!

 Albert J. Bernstein’s new book has also given tips on how to spot four  types of emotional vampire, and how to defend yourself against them, the  Daily Mail reported.
Control freak vampires are always  immaculately dressed and ridiculously organised. There’s no such thing  as a simple decision with them – the positives and negatives of every  option have to be weighed and analysed, but once the decision is made  there’s no changing their mind.
They can be loyal friends – if  they’ve promised you something, you can be sure they’ll deliver. Their  attention to detail can be irritating, but it’s frequently something  that saves time and money.
Since they’re perfectionists with a  clear moral code and expect other people to behave in the same way,  their disappointment is apparent if you don’t. Though they never  intentionally hurt anyone, anything that threatens their sense of being  in charge prompts what can be a hurtful reaction.
Paranoid  vampires are quick to take offence, and with the ability to hold a  grudge for an inordinate amount of time, they paranoid vampire can make a  mountain out of even the smallest molehill. Things never just happen to  them, in their eyes they’ve always been picked on.
While they  can be suspicious of almost everything, paranoids are fiercely  protective of their family and of one or two close friends. They have a  penchant for saying to people’s faces what the rest of us would only say  behind their backs.
Paranoids abide by concrete rules they  believe everyone else should live by, too. Their eyes are peeled for any  evidence of transgressions, and they’ll usually find it. They’re  incapable of forgiving and forgetting and are also jaw-droppingly  honest.
Party vampires are always the ones who want to drink  more, stay up later and go that step further than everyone else. They’re  impulsive, happy-go-lucky types who have no qualms about lying to get  what they want.
They’re charming, good company and fun, say the  things you think, but would never dare say, and have an aura of cool  that makes you feel special if you’re picked to spend time with them.
They’re  only there for the good times. You might think you’ve got plans  together, but if a more exciting prospect comes along, you’ll be  ditched.
Me, me, me vampires are undoubtedly very successful people, and are at great pains to make sure you know this, too.
Within  minutes of meeting them, you’ll be all too aware of their achievements  and probably of where they live — and knowing the right people is very  important to them.
They are hard to impress and can be incredibly  charismatic. Some of the most successful people in the world are me,  me, me vampires.
They genuinely are talented individuals and it’s  easy to admire them from afar. It’s not until we’re close up that we  realise how inconsiderate they really are.
If they’re not talking  about themselves, they’re probably not going to be interested in the  conversation. The only way you’re of interest to them is if you can  massage their ego, make them look good or help them achieve their next  goal.
However, they lack genuine warmth. Read the full story
