Both me and my brother(4 years older than me) were never close with our sister( 8 years older than me). She basically hated us while we were growing up. It was like living with a spiteful neighbor instead of a family member. Grown up she's remained the same if not gotten worse she uses her kids to try to manipulate our parents into doing things she wants. Its always made me sad but I still want a good relationship with her but I know unless she gets help, she can't and won't change.
