[|AI|]  Hello, Thanks for choosing Chat Doctor for posting your query. The kind of behavior you are describing appears to be part of a personality trait (Feature) and not mostly an illness. It can be some personality disorder, but then she needs to be examined by a psychiatrist. We don't know the exact age of your sister. That would have helped us in providing you a better answer. If it is adolescence, then child Chat Doctor. Hope I am able to solve your query.
