Pictures. There's somethin' unquestionably sad in that, in not having something sweet to your world. Only knowing that a thing exists through artifacts and pictures. But maybe that's a thing he can relate to; to not having what plenty would call a necessity, somethin' that they could always take for granted.

There's no sky Underground. No stars. All they got are sparkling stones. That's something some say is sad, in its own right, and - well, he won't disagree.

Not quite the same, but maybe it ain't so different.

Who says a thing can't be funny and sad simultaneously? Ain't that practically Sans's entire life?

"How is it?"
