Currently I'm trying to stream line my industry. So far a lot of my miners have just been taking breaks whenever I assign new work

.
Besides that one of my dwarves was trying to create an Artfiact out of Metal Bars and Shells. I didn't have any shells so eventually she just gave up and started moping around. She slowly made her way to her bedroom which took about half a season. Once she was there she moped around until she died of starvation. This sucked since I would most likely had gotten an amazing bone or metal crafter out of that which could have boosted my trading.
After that happened I found out her husband hadn't found out about her death yet, when he went to take a nap in their bedroom he immediately became ecstatic upon finding her body. After that he immediately held a party where a single child attended and immediately became depressed.

Later on I assigned him to be a stone carver since it was taking quite a while to engrave the walls and floors of my work area. After that I found him creating carvings of her death. I don't know what to do with him but so far he hasn't made anyone else really depressed so I'll leave him be for now.
