"Would you quit being a wanker and just give in and move up here with me? It'd be easier for you, the flat wouldn't be as empty while I'm gone and it's not like we haven't practically lived with each other since Hogwarts regardless." The tip of his glass led him to realize that his first cup of scotch was already nearly empty. Yes, fighting, scotch and poker - that sounded exactly like everything he ever did with Remus.
"Besides, you wouldn't have to pay the full lease, I've got it all under control as is; and my landlord is flexible. You could pay a quarter, I could pay the rest. Stop letting your pride get in the way." He poured himself more scotch, eying Remus the whole time. Although he knew exactly why his friend was so against the idea (and yet secretly for it), he also knew the best way to get him to move in.
For the first time, instead of angrily growling about Remus' lack of appreciation for friends, Sirius posed a bet. "Listen, I have an idea. New bet. If I win, you move in. If I lose, I'll stop bothering you every time this comes up." He grinned and took another swig of Scotch.
