DEAR ABBY: Ever since my bratty stepsister came into the picture, I feel like I get less attention than her. Just because her parents are not together doesn't mean she's so much more special than me that it's OK for her to be mean to me without getting in trouble.
When I yell at her and tell her to stop, she hisses at me like a cat and throws a fit and says she wants to go home. I'm not a psychologist, but I don't think this is normal. What do you think I should do? -- STEPSISTER IN MICHIGAN
DEAR STEPSISTER: For a moment, put yourself in her shoes. Her parents' marriage broke apart, and one of them left and has made a new life with a new family. It's possible that she's afraid you have "replaced her" in that parent's affections. That's a pretty painful thought, and she may blame you even though it is not your fault.
Talk privately to your parents about this. Ask them if they can reassure her so she won't take her hurt feelings out on you. And one more thing: Stop yelling! Yelling only escalates the situation; it doesn't solve anything.
