Once, about ten years ago I had leased 40 acres and a small isolated cabin near Pine Mountain Georgia. One day after I had lived there about a month the Land Lord who lived in Florida dropped by to inquire as to how I was liking the little place. He mentioned that his teenaged daughter had really liked spending her summers and holidays in that cabin. During the conversation he told me that she had suffered a tragic skateboard accident the year before on her 17th birthday.
A couple of weeks later, toward the end of November, I happened to ask the Sister of the Land Lord where the young lady had been buried and was told that it was quite near. Since it was within walking distance I strolled over one warm day to visit her grave. Etched in her tomb stone were the words "BE CAREFUL, I AM WATCHING OVER YOU" I thought that that was an odd inscription and went on with my walk.
The next night as I was chatting on the internet with a Lady who lived in North Carolina, we both had our web cams on and each of us was alone in our respective homes. I happened to glance at my own image in my web cam and noticed a pale smokey glow that was floating just behind my shoulder in the cam, thinking that something was wrong with my cam I gave it a sort of thump with my finger, and chatted a bit more, glancing back at my cam I then noticed an image of a young lady who seemed to be looking over my left shoulder at the cam and computer as if reading what I was typing. As I looked at her image she swung around toward my front door as if some one had just entered unexpectedly. I even noticed that her long brown hair swung away from her shoulders as she turned, I was a bit startled because I knew that I was alone and a quick glance behind me confirmed it, there was no one there!
Two days later the Land Lord made an unexpected visit and I happened to ask him if he had a picture of his dead daughter, yes it was her, the same person that I had seen looking over my shoulder in the cam that night!
On another day, after I had moved from that place (not because it was haunted, but for personal reasons) I again had an opportunity to visit her grave site and this time I read what was etched on the stone, it said "BE CAREFUL, WE ARE ALWAYS WATCHING" and there were etchings of small animals and not the words that I had first read there.

BE CAREFUL, I AM WATCHING OVER YOU.
OP's Second gravestone reading:
BE CAREFUL, WE ARE ALWAYS WATCHING.
The actual photo of the gravestone reads:
"Be careful, I'm watching."
Occam's Razor doesn't direct me to a re-carved gravestone here, but to a normal lapse of human memory. (wolf-mitchum, please don't take this personally; all our memories operate this way. It's part of being human.) That was true even before I saw the Find A Grave links.
