"Hey, have you ever heard of 'smoke in the opposite direction'?"
"What the hell?"
"It's just... A cigarette that's meant to be smoked in reverse."
"I've never heard of it, where did you know about it?"
"This kind of cigarette looks exactly like ordinary cigarettes. But if you look carefully - the cigarette holder and butt are reversed."
"How could there be such a thing? Isn't this anti-human..."
"I heard it symbolizes unshed tears and unspeakable regrets."
