When my wife was just starting into playing this game, It was maybe her 4th fortress. She embarks and makes designations, zones, and stockpiles. Then she unpauses the game and watches her miners mine out a nice cliff face while a giant mole steals ALL her supplies, EVERYTHING!!!. I facepalmed.
She gets the situation under control (re-made everything, and restocked), and in the second year a goblin ambush comes and kills everyone. They even hunted down every single dog and cat before killing the last dwarf.

I built a large walled fort with a large moat around its entire circumference. I didnt have a mechanized draw bridge accessing the fort, but a carved bridge bristling with traps across a chasm 10 or so Z levels deep...
The traps were getting cluttered with body parts from goblins, raccoons, foxes, and deer, and my dwarves were too busy to haul body parts all day... SO, I had the bright idea of creating a cistern above the carved bridge with a mechanized bridge at the base of the cistern to release water onto the carved bridge underneath, thereby washing all the bodies and limbs into the chasm where I had access to the bottom from the inside of the fort.... Bear with me now....
I had a talented marksman as a hunter, he had 2 war dogs assigned to him. These guys were awesome killing machines that usually offed snatchers and raiders long before they reached the trapped bridge...
I finally got the cistern filled to 6 deep with water, and I wanted to test it. I checked the bridge under the cistern for friendlies, and the surrounding area, but saw no one. I order the lever pulled, and I see that my much loved hunter is coming back to restock his ammo.... Hes too far away and I can see the guy who's going to pull the lever almost adjacent the lever. No worries, the timing is right I think.
Dwarf pulls the lever, YAY it worked!, the bridge is clear of clutter.
I go the the bottom of the chasm to see the product of my handy work, only to see a war dog that had been accidentally washed off in the process. Its only a war dog, the fact is got hurt sucks, but a least its not a dwarf. I check its injuries, and sadly I find its entire lower body is crushed to a pulp. The War dog doesn't die, it pulls itself around sadly in amongst the limbs and corpses of countless others for a month before I decide Its not going to die on its own, and no one is going to tend to it. It needs to be put out of its misery. I order it slaughtered and butchered (which I didn't think you could do with war animals, but apparently you could at the time, 31.12 I think). Not to long Later I check my Dwarf Therapist, and I see my hunter is Miserable. What the heck, 'It must have been his war dog', I think to my self. So I check out my hunters status... I like to have butchery and tanning activated on my hunters, because it seems only right...
Apparently he had been the only butcher available... He had dragged his horribly mangled pet up from the chasm, slaughtered it and butchered it. And moved the corpse and hide to the refuse pile. It said in his thoughts:
"He had to watch a beloved pet rot"...
Wow... I'm the worst kind of person...
