Well, that was just very upsetting! Sirius was very fragile and he could not emotionally handle being ignored, okay? What did his ego matter!
Sirius frowned and batted at the page again, tipping it down slightly so he could peer at it too, upside-down. "I want," he said, "to do something. Something without words in it. And you should oblige me, because we are mates." This was fairly mild emotional blackmail where Sirius was concerned, as was the despairing pout of utter boredom that he cast at Remus in the hopes that the other boy would look up and see it and be deeply moved.
