Players complained that Sims were ignoring the deaths of loved ones who weren't in the household so they added the phone call/sad moodkets. If it's possible, all they need to do is tone it down a bit and base time periods on the relationship. Perhaps if an acquaintance dies, the Sim is sad for 8 hours (about the same time an Embarrassed or Angry moodlet lasts for a work school negative event), if it's a friend then 1 day (24 hours) and if it's a close/best friend or a family member (parent/child/sibling) go the full 2 days. And actions like crying it out, calling the sadness hotline etc. can help lessen the mourning time.
