Brothers, A prequel to Brother

"Explain it to me."

I blink, surprised by what Sans said, "Sans, I-"

"Papyrus, if it's so easy to understand, explain it to me."

I think for a moment. How do you explain being happy? "I've always felt that if I'm not happy, you're not happy. And, I guess that it's hard to be an optimist when you're always the only one."

"Papyrus, then why do you force yourself to be one," his soft voice speaks the question as a statement. "You force yourself to do too much."

"Sans, I'm only an optimist because I have to be." I think about catching Sans at night having panic attacks, seeing him drink himself crazy some nights because of something dark in his past, because of something dark that he always refuses to tell me. "You don't tell me anything, Sans."

He chuckled a harsh chuckle, "sometimes, it's better that way."
