I suppose Harry evokes this feeling sometimes. What if I'd lost my most favoured parent as a child, in my case that would have been my mother. Looking back I loved her much more than my father who was quite emotionally detached and I think hell, if I'd lost my mother as a young child and had to have relied on him to raise me, I'd have ended up a basket case. Even as an adult my mum was my lynch pin. How do you think you would have turned out if that much loved parent or even grandparent had suddenly disappeared from your early life, would it have had a catastrophic effect? Or maybe both bestowed their love equally or maybe neither did.
Mummy removed from museum due to lack of consent!
On a slightly similar note, I read Jack Nicholson the actor was brought up believing "his mother" was his sister
