Some people you simply love to hate. These can be at office, can be acquaintances, can be relatives as well. They come in all ages, sizes and quantities. Being utterly irritable is their basic property. Some other properties seen are- being chipku, being high-handed, taking all limelight, taking credit for others. The list is not exhaustive.
Dealing with such people mostly makes you lose your temper and frustration mounts on you. Visible side effects are making faces behind their backs, not answering their calls and pretending to be busy when approached.
More inputs are welcome!
