Is working in a graveyard lonely?

Tweet

While crawling around the web, I happened to come across a historical article about Ted Brook, a former member of Jubalaires, one of early gospel groups that sang in a rap-like style. Seemingly the story was shared by a graveyard gardener in Mount Olive Cemetery, a Jewish cemetery in Solon, Ohio USA. Crawling further I realized there were job openings. That sent me wondering how it is to work in a graveyard. The silence, the loneliness, and possibly the fear. I do not think I can comfortably work in a graveyard. I lack the courage required.
