I turned my game on the other day to find both parents deceased on the bed, and the 16 year old triplet boys surrounding the bed, "mourning" them.
Then they immediately went out and spent their inheritance on a pinball machine.
I had the mourning thing happen to me the other day. I think it was my first family. The wife died, waved at me and the husband was stood at the end of the bed, mourning the dead. I don't think he got depressed after either.
