On one tour there was this loud mouth sceptic, who seemed to be ruining the tour for the other 14 people. At one extremely haunted location he starting taunting the ghosts to show themselves to him. We were trying to ignore him and carry on with the tour, but it really did get too much for us and the rest of the tour party.
So we gently asked the resident ghost to show herself or give a sign that she was present, but there was no response this night.
About a couple of minutes later the loud mouth was eating crow. All of a sudden this ghost was seen standing nose to nose with this man, and it was a toss up who was whiter.
He started trembling, sweating and extremely fearful and had to be carried back to the waiting coach. Thankfully the rest of the night went smoothly as he kept his mouth and his opinions to himself.
Apparently this particular spirit doesn't like sceptics and will play with do things like poking them, or tripping them over. I suppose it's his way of saying here I am and I do exist.......
