Sister can kick rocks

The sister can kick rocks. She just rubs me the wrong way. As the youngest sibling my sister does confide in me about her relationship and issues. Of course, depending on the severity of the situation, she may wait a few weeks to months to process. But she will still tell me at the very least vague details regardless if I can help or not.
His sister is ridiculous, she chooses not to confide in her brother but when he mentions Kang all of a sudden she wants to talk.
