Heh, I had a mood just last night, a glass maker (I sense a pattern!)
The thing is, I had a fort in a layer of sand with a pair of magma glass furnaces, so I figured I would be fine, except she didn't go for either magma furnace, she wanted a regular one! So I built one in an empty room off my main stair well, and she promptly went for it. Then sat there demanding cloth... crud... wait, I just bought some silk cloth off of the dwarf traders, she couldn't possibly want... plant fiber cloth? so I draft a peasant into plant gathering and build a loom and start searching for rope reed... nothing, nothing.... human caravan shows up, yay! they should have some cloth, surely!
I start moving goods to my depot, but my trader is attending a party, and the merchants arrive and start onloading their goods... and my glass maker picks that exact moment to goes berserk... five or so tiles away from the stairs that run the height of my fortress... fortunately, I'd just begun training a military, and I had four no title marksdwarfs that I quickly put on duty and assigned to stand in the stair well.
Did I mention that all my dorfs are proficient or better in all social skills, and my glass maker was carrying her baby with her?
The glass maker takes a moment to kill her baby, giving my marksdwarfs time to get to station on the stair well... they manage a few shots before she's on them, and she manages to injure one of their legs before she goes unconscious, and I don't know HOW no one fell down the stairs, which go all the way down to the lowest Z level, where I have my catacombs... a good 8-9 z drop from the level with the glass furnace.
As of this moment, my trader is STILL partying in the dining room.
Luckily, I suppose, I've only two casualties for now; the glassmaker and her baby.
