Bro, siblings would take ur food and ur stuff, would blame u for things they did, they would want u to play with them even if u don't want to, there get u in trouble if they don't get what they want, they will act weird in front of other people in front of u, and other stuff
But I'm always bored as hell, having nothing to do, and my mom says to at least get up and do something- but like- idk wtf to do, and at least having siblings would make you active and shit, and always doing something, and I'm just sitting in my room, drawing random shit lol
