Remus / Sirius
That was Sirius Black for you; just incredibly thoughtful. Ask anyone.
Sirius liked the lists. He knew Remus had more mental ones going on than he did physically written ones, but there was just something so charming about finding paper every once in a while, all checked and crossed out -- like the completion of the list was part of the list itself.
It never failed to make him smile.
He sipped his drink and waggled his eyebrows at Remus before leaning over a little and peeking at the list. "Is that really on there? Sirius' enjoyment: paramount'? That's too kind, Moony." He kissed noisily at Remus' cheek. "I think you could. Check it off. But maybe it should wait 'least til we dance."
