Papyrus nods a vigorous confirmation. "I am! I'm Papyrus, and Sans is my older brother. I guess, from his perspective, it's been a few years since he saw me..." His foot starts tapping, the frustration needing an additional outlet besides his too-loud voice. "He knows I came by, I've brought him a letter every day--!"

He catches himself before raising his voice to outright shouting. "But! Please do. Maybe it'll sink into that thick skull of his that I'm really here if somebody else lets him know. And then..." What will happen then, Papyrus doesn't clarify. He just grinds his teeth a little harder.
