Death

Can't really pick an option because for me it's kinda all of them. Sometimes in the Sims death is fun (I might even deliberately seek it if I'm bored), sometimes it's sad when I'm letting go of a dear old sim, sometimes I avoid it altogether (like turning my favorites to vampires i.e. immortals, or reloading a save if i somehow managed to get them killed) and sometimes it's just a normal part of life which happens when it happens whether due to an accident or natural causes.
