Sirius snorted at his brother, amused they'd been able to keep this up as long as they had. "I don't need to tell myself anything. I know how good looking, charming, intelligent, and all around awesome I am."
"Which is exactly why we need to get you into a pair of jeans straight away." Sirius told his brother, nodding safely at the statement. "It would do you a whole world of good, and as you said you do like to indulge me." Really it was quite logical, Regulus should just do it, as it would make them all much happier.
"I'm glad you realize this about me, so many people misjudge me, but I really am very sweet and of course completely innocent." He couldn't help laughing though, at the absurdity of this entire situation - he and Regulus teasing one another. "Then infamous it is."
