[ The comment on patience gets Sebastian to laugh shortly, but still good-naturedly. It seems that he either completely agrees or completely doesn't, but either way, that good-natured laugh seems to imply a story behind it. ]

Well! It is an acquired skill, I must admit... I am certain that I would be less patience if my patience were not tested every day by the rest of our serving staff. They are quite miserably incompetent, so I take care of everything myself, you see.

[ Which... he seems to be fine with? Maybe he's found a new level of patience all together with an answer like that. ]

Ah, but it is quite all right. There is no offense taken, for I will hardly disagree with your assessment... I do seem to be a bit out of place. [ He laughs, though his humor here is mostly because he's actually extremely well-suited to this. It's just also not something he's keen to advertise. ] If anyone is in need of chores, cookery, or other sorts of menial tasks, I would think I am well-suited, at least!
