The ghost has appeared in our home, as well. I imagine this has something to do with the dead people who once lives here. They may have liked tea more than coffee. It seems like we will make coffee, then an hour later the hot water turns on like someone in the afterlife is pressuring us to make them something else. Have you noticed any other issues? Does it only go on when you don’t make Starbucks? Does the fridge door open if you forget creamer? I’m determined to catch this ghost. I have set up some traps and a tape recorder. Someone should get ahold of those guys on Discovery or History Channel.
