Kira-kira 12-13 chapters response

Katie began to feel angry when Lynn ordered Katie too much. Katie was really tired after taking care for Lynn for days and days, Katie was getting tired and stressed with waking up in midnight to give her sister what she wanted. Katie even got black circles under her eyes. Katie usually woke up directly when Lynn called Katie. But this time she was very exhausted but barely pulled herself up. Lynn ordered her to bring milk. But when she brrought milk to her, she made her face and instead asked for a glass of water. She dropped the cup on the floor and the rug her father bought lynn soaked all the milk in. Katie becamse quite mad and said dad had to buy her. After bringing the water to her, she said there was soap on it and flung it to the floor. Katie, finally becamse angry and said she is ruining everything in the new house which her parents work hard to earn it. Lynn seemed hurt for a moment but then got angry and ask her for milk. Katie replied no. They both said "I hate you" to each other. I think this happened because both Lynn and Katie is going throught adolescence which makes her more sesitive and easy to get angry.
