Stop Grim from asking if you want to be a household or free-roaming ghost?

Thank you for responding. I understand the terminology of the ghosts. I was asking how to stop up that pop up. It gets annoying to see every time a Sim dies. It's like the Emily popping up, asking if you want lessons in the Sims when you are a seasoned player. You already can make a Sim a member of the Household by clicking on the gravestone. It's seems unnecessary repetitive.
