This story is told by my mother. The story goes like this.
One night, my grandmother & grandfather had finish watching a movie around 12 midnight. At that time, it was really dark. My grandmother really felt scared but my grandpa just maintained his step but my grandma really in rush.
While they were walking, they saw a swing, was swinging itself. When my grandma saw it, she quickly run. But my grandpa not just standing doing nothing, but talking to the ghost. He said to the ghost to stay away from people and don't disturb them if they don't disturb you.
Then my grandpa and the ghost live.
