The Secret Ghost

I was told this story in the strictest confidence.  Of course,  I am retelling it, but I am omitting all names and locations and since I know people all over the nation (even a few in other nations),  I believe there is no way it could ever be traced back to the teller.  A friend of mine who has known for a while that I love ghosts, was telling me about her real estate woes.   She has been trying to sell her house for a long time and has had no success.   In the course of discussion,  she became very nostalgic about the house.  She described how beautiful it was and how, when she bought it,  she had dreamt of raising her children and growing old in the house.   She described it as spacious and beautiful.  It had a pool and lots of land for her children to run and play on.  It was everything she had ever wanted and more and she couldn't understand why it hadn't sold.

So I had to ask, "Why are you selling?"  She hesitated and then told me that it was haunted.  I tried, using all powers of persuasion to get the dirty details on the haunting from her, but she didn't want to talk about it much.  She certainly didn't want it ending up in my book or column.  She believes that if word spreads that the house is haunted she'll never be able to sell it.  She did tell me that the ghost wasn't that belligerent.   It was just always there.  She worried about her children and the impact that have a presence would have on them psychologically and I got the distinct impression that although the ghost wasn't harmful, it certainly wasn't nice.  She didn't want her children to grow up afraid and she felt the ghost filled the house with fear.   She said nothing else.  

The family has already moved and purchased a new house, but the economic ramifications of owning a house that sits empty are large.  She worries about her secret ghost and her empty house and worries that the secret might get out.  Which brings me to the larger question,  should the ghost be secret?  I feel her pain, but what if another family buys the house and then has to go through the same pain?  Is it fair to keep something like this secret?
