I just don't get it - part 1

Yes, part one because there are so many things I just don't get.

This one is about behavioral patterns, so I should imagine there'll be more repetitions of this than anything else. What I don't get is this: the grown woman who behaves like a spoilt child - you know, the one who talks like a gobby teenager mouthing off to her parents or like a petulant idiot who thinks everything revolves around her. The one who's raison d'etre seems to be attention-seeking, who takes her bad mood out on those around her (while claiming that not only does she not do it but other people do) and who is incapable of taking responsibility for her own actions. Then there's the bloke who always has to push things - he likes to wind people up and will joke around as much as possible, even to the point of upsetting others. He's the guy who'll ask if you want a drink and, on hearing 'no', will always ask 'are you sure?' - not because he's interested in buying you a drink, but because he knows the question (repeated if necessary) will annoy you and that's what he likes.

The 'woman' is obviously still a spoilt 12-year-old used to being Daddy's Little Princess, emotionally speaking, and the 'man' maybe around 14 and conversely likes to play power games with Daddy, although I know someone aged 15 who's been a wind-up merchant since the age of around 7 and I know full well it's down to his parents. The questions that arise from this, for me, are: why do some people get stuck in particular behavioral patterns from their childhood? What is it that anchors people to a point in their past? Some people have a traumatic experience that acts as their anchor - maybe all of them (us?) do, or maybe the experience doesn't even have to be traumatic to be the thing that holds a person still, stops their growth, fixes them at a point in time. What happens to people to cause this arrested development? How many people are even aware of that part (those parts?) of themselves that remain unchanged from childhood? How many have even the vaguest clue how little of their potential they're going to fulfil thanks to that one thing holding them back?

For me, the most important question is typically selfish: what's mine?
