Poltergeists are usually associated with children and teenagers - neither which we have living in our house.
And yet we have a poltergeist in residence.
My husband has a tie pin which is very old and of Indian origin.
He wore it to a wedding some time ago and after the ceremony took off his tie (he hates ties) and inserted the tie pin into the tie which he placed in his pocket. i saw him do this.
On returning home he changed out of his suit - it is far to hot to wear here! Took his tie out of his pocket - and guess what - no tie pin - he thought he had lost it. we looked in every pocket and it definitely was not there.
The suit was worn again - no tie pin in evidence.
We were going out one evening and he went to put on his suit and - the dreaded tie - the tie pin appeared in his pocket!
This is just one of appearances and disappearences that happen on a regular basis in our house.
