while at work one night, was taking care of an old lady that was complaining of chest pain. she was talking to an old man that I figured to be her husband, seemed like a nice old man. he gave me some information about her. after talking to the lady some more, I turned back around to talk to him, and he was gone. I figured he went to get some things for her to take to the hospital.
then, this lady's middle-aged son walks in the room, I ask him if the old man "bob" went to get her things. he looks at me real weird and says that his dad, named bob, died about 10 years ago, and no one else lived in the house. creeped the eff out of me.
on the way out of the house I saw a picture of the old lady and her dead husband bob, the man I saw was definitely him.
I'm not saying the ghost was a mean guy or anything, but up until that point I had never thought of ghosts as being real. now that I know they are real, I'm sure there are mean ghosts out there and I want nothing to do with them.
