In my family there are certain cliques that bond. Outside the ones who are close since childhood I notice they stay really close to someone they think can do something for them. It seems like an ugly thing to say and I may be wrong for it but I m not sure how else to look at it other than there was a lot of favoritism growing up and we can't really say or do anything about certain siblings no matter how bad their behavior. So I think there's more going on than just not as close... Why aren't you as close what is preventing you from having the same kind of bond or Love.
