"Hey, Reborn? Not that I want to question your teaching methods - though I do, constantly," Tsuna takes a deep breath, "Shouldn't you have started from teaching me all this etiquette stuff? I mean, instead of shooting me with a Dying Will bullet and forcing me to fight and embarrass myself and protect my friends, couldn't you have started from the easier, er, non-violent stuff, like Italian and how to use- whatever this thing is called again."
"A tie bar, Dame-Tsuna. Forget it again and I'll shoot you with a real bullet."
"Yeah, a tie bar. What I mean is that this stuff actually kind of makes sense and you're just trying to teach me how not to make a fool out of myself in a polite company right now. I'm just wondering if it wouldn't have been easier to let me have a vague understanding what the job entails first and then teach me how to fight?"
"There's no point in grooming a gentleman who can't survive."
Tsuna tilts his head. "I don't understand?"
"That's why they call you Dame-Tsuna." Reborn sighs. "Would you have survived Mukuro by knowing how to use a tie bar? Or defeated Xanxus with a few Italian compliments?"
"I... guess not?"
"Would you survive a Mukuro-like incident while knowing what a tie bar is now?"
It takes a few seconds before Tsuna's face lights up with understanding. "Oh. That actually makes sense." He cringes. "Though, I will never repeat any of those Italian expressions you're forcing into my head to Xanxus."
"Why not? The result would be hilarious."
"I would die a slow and painful death."
"Yes. That would be the hilarious part."
"Andthis would be the part where I question your teaching methods."
