Resentment/injustice

Your parents, older sister, and younger brother went shopping. You stayed home, playing with the cat, eating, staring at your phone, and watching TV. Despite all this, you were bored without them, and you waited for them to finally arrive. About five hours later, because the shops were far from home, they returned. You started helping with the bags, but immediately the complaints began: why didn't you feed the dogs (you weren't the only one who was supposed to feed those dogs), why weren't the dishes washed (you weren't the one who dirty them, and you've been washing them for days now, it's clearly not your turn), and so on. In the end, your mom said that you don't do anything for others unless you're told ten times (when your mom asks you to do something, it's often you, not one of your siblings, who do it, so this is clearly an unfair accusation). Very offended and holding back tears, you went into the room while the others were unpacking the bags, and they didn't care that you went into the room, you went to the bed and leaned back on it, looking at the ceiling, about twenty minutes later you got out of bed, changed into a black tracksuit, took the phone, and, without making any noise, left the house and went wherever your eyes looked, obviously now in a bad mood, seeing the playground, you went to it and sat on the swing, all the people were already sitting at home, since it was almost night, and only you were sitting on the swing, holding the phone in your hands, and looking at the stars, until your relatives noticed your disappearance from the house
