Given what they're talking about doing, Yoongi figures it's probably unfair of him to judge anyone else for doing the same, but that isn't actually stopping him.

"Isn't the real question whether or not you can be quiet?" he teases. Jungkook is perfectly capable of keeping it down when necessary, but Yoongi likes all the noises he makes. Still, that's part of the appeal of being in public, the need to be careful, the risk of getting caught. They could get in a lot of trouble if they're not cautious, but that hasn't stopped him from doing things in the past. Why would it stop him now?
