A couple told me their first son kept talking about Bobby. Bobby this, Bobby that. Their second son born a few years later went on about Bobby too. Sometimes Bobby would keep them up half the night. Now they start looking for an explanation. They lived in a trailer they had moved on to the lot because the previous trailer was destroyed in a fire. What they found out was the owner had died in the fire. His name was Robert. I asked how long this had gone on for. They said until they moved, the oldest was about 12. Sometimes the answer is not in the building but in land underneath it.
