This is another episode that occurred when I lived in Poston SC, which is where I grew up. When I was about 12 or 13 years old, I was riding home one night with my Granddad, who was driving, when I spotted an old guy walking on the right side of the road facing the car.
As we approached him, I noticed that he looked a lot like a distant relative named "Buddy" who had died about a week or so ago. Buddy had severe arthritis in his hands and tended to walk with his hands up towards his chest. The guy on the road had the same affliction and as we passed him, he threw up one of his crooked hands and waved at us. I didn't say anything to my grandfather, but I'm sure he saw him too, and I just dismissed it as someone who looked an awful lot like Buddy.
Some years later while I was in the military, I came home on leave to visit my relatives and we were sitting around talking about ghostly experiences we've had. My sister mentioned that, while riding home with our grandmother one night, they both saw Buddy walking along that same dark road and he waved at them. She said our Grandmother was driving at the time and when she realized that she had just seen his ghost, she broke all kinds of traffic laws trying to get home. It wasn't until my sister told that story that I realized I had actually seen Buddy's ghost and not someone who looked like Buddy.
Poston is a small rural area with not a lot of people living there. So, I guess I should have known that there couldn't be anyone else there that looked like him. But, when I saw him on that dark road that night, he looked like a solid, flesh and blood, person; he wasn't transparent or anything like that which would indicate he was an apparition. My granddad probably knew he was a ghost, but didn't say anything to me because he didn't want to frighten me.
