We had a ghost in our house when I was a teenager. Nothing scary.
I did the research after our neighbor told us about a man being killed there. He was home from Vietnam and wanted to surprise his wife and family.
They woke up scared, shot him through the door, and he died on the front porch.
He would come back from time to time, and check on my brother and I.
I always wondered if he thought we were his kids.
