Sasuke huffed out half a laugh, amusement still in place at the corners of his lips; he wouldn't nod, of course, any more than he expected Kakashi to genuinely spend time ragging on his teachers (that was something more Sasuke's right in any case), but the mention of good habits made him grin a little. "I suppose if I master all of your techniques, no one will care if I show up to everything hours late."

Not that he expected anyone to actually be patient enough to wait for him the way he'd waited for any of the people who had taught him in any formal capacity over the years -- he was reasonably certain that the last lesson he'd had that actually started at an appointed time was sometime during his Academy days.

That last question made him straighten away from the counter, however, aware again of how he was imposing on someone else's hospitality with the unfortunate after-effects of his own bad decisions. Hoori ruffled his feathers on his shoulder at the disturbance, settling again with an ill-tempered chirrup.

"No, I've already received more than I'd expected when I left home this morning," he said -- more formally than he'd intended, maybe, but genuine. "I shouldn't take up more of your time now."
