"Regulus. My name is Regulus. Not Reg, not Reggie, not any abbreviation you can come up with at any given time," he said, exasperated.
"Comics? Are those the Muggle books with pictures?" he asked. "I put them in a shelf with other Muggle books, although I don't understand them. There is no way that Muggles can do what they claim to be doing in those comics. Controlling iron, flying with no brooms, splitting into more version of oneself. Even with magic, you can't do that. Also there is no way those women can stand up with the size of their breasts. They'd tilt over." He really didn't understand Muggles.
Regulus looked at his brother. "Well, if you don't want to be a Black, then feel free not to have anything to do with me or anyone in the family," he said, annoyed. "If not, shut up and stop arguing like an idiot. I'm not Mother and I'm not going to get into screaming matches with you. I will not give you a reason to walk away and blame me. You want a family, you have it. You don't want it, then it's on you."
