Like Mother Like Daughter

My sister decided not only to go home several days early but to leave at 9:30 at night without saying goodbye. I was exhausted and sleeping, Wood watching TV, Twig hanging out with them. She just packed everyone up and drove away. I'm so disappointed. It's so rude! And I told her that it sucked that she left without saying goodbye or letting us say goodbye. Because we were really looking forward to spending time together tomorrow. Maybe we offended them? Hey, my mom did it, too - walked out, no words, just left. I guess I shouldn't be too surprised. Now I'm just mad.
