[Every time they touch on Alberto's childhood, Katsuki gets the sense that it's a giant can of worms. These little details sprinkled throughout their interactions sure paint an interesting and kind of sad picture even without the whole story.

He eyes the knife being held out and, in typical Katsuki fashion, can't just leave details like that lay. He's careful taking it, but makes sure to point out;]

Never offer the sharp end like that. Someone isn't looking, they'll get hurt grabbing for it. Shouldn't run with sharp shit either.

[Little things. But important. And the kind of details he pays attention to. But he doesn't harp on it or raise his voice like he has in the past correcting Alberto. He's come a long way since that day in the woods of Stardew Valley. Still firm and gruff in tone, but he's not yelling now.

He does as he's instructed, tip of the blade catching a seam and popping the stitch.]
