Tobirama would never admit that, even if it was indeed taxing. He'd make quips about it in heat of the moment situations when someone was particularly irritating (hint: Naruto). Outside of such instances, though, Tobirama was the suffer in silence type. In the end, if there was even a modicum of good that came from all the blood he shed, the work he put in, then it was worth it. He'd done his job. He brought Konoha to prosperity even if the choices of those he mentored does, inevitably, fall on him. The many things he'll never speak without some teeth pulling. Pride.

"By all means," comes with a nod, the tea cup returning to his lips. Something heavy, Tobirama imagined. With the way he's looked away and saddled up himself just this moment.
