I have a view on both sides.
If someone said that to me, yes, I'd distance myself from a lot of interactions.
That said. My oldest sister is a very difficult, sometimes hateful and always loud and self centered person, i love her dearly. Because she is my sister, and it's just way she is.
I also know that if she was someone I met off the streets, no, we wouldn't be friends. Or even like eachother. But nothing in this world or anything she ever did would make me tell her that. That would be unfeeling on my part.
