I can’t stand my step sister

I am here for only like a week. Since my mom and dad divorced and we live in another city ı come to my dad’s house only for a month in a year. But it is so crowded in the house. My step-mom’s mother, sister, her sister’s children. It is full of chaos. And besides all of these my step sister is acting like a damn teenager she is. She is 15 but not that stupid. Girl you are not a child anymore grow up.

Anyway ı act like everything is okay because ı will return to my home in three days you know. She is just a spoiled brat and does nothing when it comes to house. She is just messaging to her friends or her bf. And ı don’t have pity for these people who does nothing for theirselves. I will just sit and watch when she ruins her life in the future.
