I do.
They are usually highly entitled, self absorbed and think that the entire world should revolve around them. I've met many people like this in my life, but two stand out more than the others.
The first was a boss I once had who, despite being in his late 30's would throw actual temper tantrums when things didn't go his way. He would literally stomp his feet like a toddler, we all used to call him "Kevin" after Kevin the teenager from Harry Enfield because that's exactly what he was like. His Mummy and Daddy had founded the business, they'd given him a management job right out of school despite him having no experience at all. He'd never had another job and lived in a house that was in his parents garden. He had deputy manager who was far better at the job than he was and who kept the place running, but he never gave her credit for it.
The other is the daughter of family friends. Very, very spoiled growing up is now horribly entitled as a result. Can't keep a job for more than a few weeks at a time, goes through friends like hot dinners and can't keep a boyfriend for very long either. She's so high maintenance and believes everyone is jealous of her and that all men fancy her, this is because her parents have conditioned her to think this way. I actually worry about her, because if god forbid anything were to happen to her parents she'd be up shit creek without a paddle.
Don't parents who spoil their kids realise they are doing them a terrible disservice?
