How can you put a stop to an overbearing sibling?

Am the middle child of 17 but we have one sister that stands out for her bossy tone and tantrums (she's 47). Unfortunately, people like this always have the right answer and are seldom wrong so pointing out the behaviour won't work. I avoided her for years and now live 1100 miles away and find hanging up on her the best way to avoid listening to her tell me how I should be.
