The Black Thing

A story my mother told me from long ago. It's something my mother heard from a colleague auntie when she was working at the factory mentioned in my previous post, 'True Story'. Apparently, when that auntie was sick at home, a black object was running around and circling inside her room. When the auntie was surprised, the black thing turned towards her, said 'I'll be back,' and then disappeared. I haven't heard what happened after that, so I don't know. I wonder what became of it.
