Okay ... I went online using my phone just so that I could let my frustrations out.
Spoiler
So my sister was supposed to wash the dishes today. Lunch and Dinner.
She didn't wash the dishes during lunch because she said she was lazy. She might wash them later so I let it go.
When dinner came, she hid in the bathroom so I washed the dishes. I only washed the dishes for dinner because I wanted to show her that I refuse to do everything in her place if she got lazy (which I already did a bunch of times). I also hoped that she won't go back on her word on washing the dishes for lunch.
When I got back, she was watching the TV in the dining room and our dad was washing the dishes.
He got mad. So now we're told to cook for our own selves, wash our own dishes, and buy our own food if there are none at home.
