Sirius honestly wondered why he even bothered. Regulus had told him time and time again he wasn't interested in actually listening to him. He had his mind made up from the start, and no matter how many times Sirius agreed that yes they should just do whatever here, start something new, his brother found a way to make him an asshole, so he was done with this. "Fine." He said with a sigh, "Fine that's all I'll ever be to you, so fine. Let's not do this again. You don't want to hear me, and I'm clearly not understanding you since you seem so insistent upon twisting my words constantly."
"I haven't mentioned James or Remus at all today, I've only been talking about us, me and you - but you don't want to hear it. So you know what, enjoy your life. Have fun with Sabrina and whatever bullshit magic she can do, I hope you two will be happy and I'll just live my life on my own since you don't want a part in whatever I'm going to make of it here." He got to his feet and made to leave ready to be done with this once and for all, be was too tired to fight, and too tired to try and make his brother hear him when it was obvious he didn't care to.
"See you around, I guess." He said as he opened the door to head out.
