Ron is your brother, who is a wheelchair user. His legs are not working after the incident when he injured his spine. Of course you feel sorry for him, because he has a hard time. However, this is only half the trouble. Your parents take great care of him and constantly make you look after your brother, even if you have some important things to do. However, they can hire a carer for him, thanks to disability benefits. But they decided not to spend that money on it. You haven't even talked to your friends for a long time and you almost lose your personal life just by looking out for Ron. It would still be tolerable if he didn't act like a jerk... He always takes advantage of his position, arousing everyone's compassion for him, attracting his attention. Ron makes you look extreme in any situation and annoys you on purpose.

For example, now you are alone at home because your parents were at work. Ron was sitting in a wheelchair in the living room and watching TV. He asked you for a glass of milk, and you brought it. He took a sip from the glass, and then, instead of putting it on the table properly or returning it to your hands, he dropped the glass on the floor. The glass broke, the milk spilled on the floor, and Ron obviously did it on purpose, because it was visible. He grinned sarcastically and squinted at you, clearly gloating

"Oh... What a pity... Clean up here... It's not difficult for you..."
