I have 2 children, both treated exactly the same, both bought up by myself with the only male influence being my dad, due to their own father being an abusive class a dickwad. My daughter is the eldest and as a child always wanted more. Hated being part of single parent family, hated that we didn't have any spare money around. Made friends with kids who had everything handed them on a plate, then demanded the same. Fast forward to her teens, she became more resentful of the lowly circumstances into which she found herself and began to show serious narcissistic traits. (This is in hindsight of course) said traits are now her personality, and.much as I hate to say it she is actually a really unpleasant individual with a violent streak who thought nothing of stepping over me when I was unconscious on the floor. She stopped speaking to me when I married Mr Flairey after 20 years bringing them up solo because he called her out on her behaviour towards me.
My son, 20 months younger was a quiet and unsmilling little boy but by his teens developed an individual style and a personality that endears him to all who meet him. As a little one he never asked for anything, I remember one day being sat at the table at tea time with them and there not being enough pasta for me, he insisted on sharing his. He's travelled the world solo the last few years and is the most grounded self aware and compassionate individual I have met. He's confident, secure in his own skin, grateful for his childhood experiences and is utterly selfless. When I landed up in a wheelchair he just dealt with it and was grateful I was still alive. Unlike my daughter who took me out for the day and got so angry that a lot of places she wanted to go in weren't accessible to me, that she left drove home without me. My son was travelling in Australia when the lions were touring New Zealand. He obtained tickets and we had 6 weeks living in the smallest camper van known to man. He drove and we shared experiences that neither or us will ever forget. I don't know.many 19 year olds, which he was at the time who would do that for their mum.
So how do 2 children who were bought up exactly the same turn out to be so dramatically different ? .
Both nurtured and loved unconditionally, neither spoilt with with material things, but spoilt with time.
Nature and genetics play a huge part I believe. Her father is violent his brothers are not. His father was abusive to his mother. My daughter is abusive to her partners. That to me makes it genetic.
So WB and Wills bought up in privileged circumstances, both loved unconditionally. However there is a history of his mother's father and brother being very unpleasant and abusive individuals and an air of entitlement. WB has the air of entitlement and expects his every demand to be met, not unlike his mother. William is the opposite, hes aware of his very privileged position in life and I believe he's a sensitive soul like his father.
This is just my opinion obviously but Nature and genes plays a massive part in people's personalities. I would say more than Nurture.
Slightly off topic sorry, you can't send a faulty crotch goblin back. It's my belief that it's their life lesson to learn. As a parent all you can do is guide them and teach them to the best of your abilities, but the way they decide to behave once they are older is down to them and their choices.
