my sil is about to get knocked the fuck out. so out studio is by her room and she has a sliding door. well my daughter went and opened her sliding door and she started screaming at my daughter saying she needs to learn how to knock.. really coming from someone who just walks into the studio like she owns the place at 5 o'clock in the morning trying to wake my 3 year old daughter up. and then she pushed my daughter out and locked her sliding door leaving my daughter out side to cry
