Jack comes to sit beside him, leaning against his side and ducking under his arm, tails shifting and wagging behind him, head tilted into the petting. He's never been petted before in a shape other than human. It's... nice? He normally gets twitchy about being treated like a dog, but this is Serph. Serph doesn't even know what a dog is.

The question pulls him up, though. "Me, personally? Or people, in general? There are lots of traditions, depending on what part of the world you're from. And of course, most of the time you feel sad, if you knew the person, or they died in a way that cut their life short." Does Serph know people can die of old age? Jack has no idea.
