III. Gilbert Nightray
Gilbert had a habit of slouching which I helped reform. I first noticed during one of my visits; it must be one of those commoner habits that the Vessalius household never properly trained out of him, which is obviously a sign of lax management on Lord Zai's part, considering Gilbert was supposed to know better manners as one of the upstairs staff.
The process was alarmingly simple, actually. I had stayed at the manor for an extended period during the hunting season. Upon leaving for a morning ride or an evening hunt, whenever I would catch Gilbert reposing in one of those moods of his in the library or the parlor or even while eating alone in the kitchen, I would slip behind him unawares and bark in his ear, "At attention!" with a snap of my riding crop upon the nearest surface available (usually the back of his chair, or the tabletop right by his hand). After a couple months of that, his posture improved greatly, and he'd always straighten up his form upon seeing me for years after.
