Thanks for the reply.
I don't use any mods. I've fixed/repaired the game already before posting this. I've never moved household. Thanks for that link, too. I had seen it. I did some small amount of research and investigating before I posted this. I find that most issues I have with the game are already out there and solved.
I have never gotten any fan mail, and I think I am always home when the mail delivers. My sim is an entertainer, so she is in bed asleep every morning when the mail carrier walks by. I'm not entirely sure when mail is delivered, though, so I could be mistaken on that.
