My sister is being abusive toward people again, including my dad.

My dad yelled at her because she almost ran over a guy crossing the street with a baby in his arms. He wasn't in a crosswalk, but apparently she was driving 50mph in a 30mph zone and said, "I don't care. There's no crosswalk," and came within like 1 foot of hitting him. (Apparently it was VERY close.) And then she almost hit someone at a stop sign about 2 mins later because she didn't stop completely or look both ways. Now she has been yelling at my dad and saying he's an asshole for telling her how to drive. blah blah blah. And she says he's a POS who clearly doesn't love her. Then my dad said to her that she is being abusive and needs to be respectful. Now she's saying that he's an asshole and that he doesn't deserve her respect.

My sister never learns. She always treats people like trash and doesn't care about consequences. She expects everyone to give her what she wants and let her do what she wants. All she cares about is herself, social life, and material things, sadly.
