Are children who grew up with grandparents spoiled and distant from their families?

I grew up as an only child with great grandparents until I was 11 – secluded from my mother’s and father’s sides of the families, and my siblings. I have always felt I was different from my family, raised in a better environment, with better morals and respect for people.

Talking to others, if they’ve had siblings who grew up this way, they feel that the sibling thinks they are better than the family, and the sibling wants nothing to do with the family (I am accused of thinking I am above them and I actually dont want anything to do with them anymore).

I was shocked that they described perfectly the things my family says about me (siblings especially) & said that is always the case with kids who grew up like I did..“Spoiled” they say.

In your experience, have you found this to be the case? That children who grew up in this manner feel distant from their families and feel they are “better” than them?
