Okay, I'll give an actual quote now. Don't think anyone's used it yet:
“And I continue standing here at the counter hoping one of my favorite customers will appear… And I wasn’t wrong. See? You stopped in”- Mr. Barten, Majora’s Mask
I've always found Barten to be the saddest character in all of Termina. When the world's ending, everyone goes to see their friends and families, but Barten... well, Barten has no one, so he continues doing his job, attending a near-empty bar, being lonely. The only connections he makes with others are with his customers. He's only known Link for 3 days at this point, but he feels friendship with the boy... or, at least, the closest to friendship he has.
