What she should see now is that if her dad had supported his children and their mother, there would not be such a disparity between her parents lifestyles, so any animosity should realistically be towards her dad.
Isn’t it interesting?
I find the concept of nature vs nurture very fascinating. I’ve seen siblings raised in the exact same conditions turn out to be incredibly different people.
Personally I feel character ultimately decides who we are. Lydia’s character is that of a spoiled princess with delusions of grandeur. She can’t help but envy others. She loves things so much that she can’t see past the fact her father chose not to provide her with his lifestyle.
She shows no gratitude for her mum putting a roof over head regardless of whether she was a perfect mum or not. Instead of priding herself on working hard and making something of herself she lives a life with a sense of entitlement. She believes she is so special things should just be handed to you.
If we were just the sum of our experiences someone like Lydia would be very independant so she doesn’t fall into the trap her mum did. Lydia is who she is because of character flaws and the fact that no-one smacked those flaws out of her.
For me becoming an adult and functioning in the real world gave me a whole new respect for my parents. I hope for Lydia’s sake she makes peace with her mum and accepts and respects both her parents equally. Parents are humans and flawed.
