A little boy asks his father:
- Dad, do you believe in ghosts?
His father answers him:
- Of course not. Ghosts do not exist.
The boy then says:
- But Mom told me that she had just seen a ghost.
The father then said to his son:
- Pack your bags, we must go away as soon as possible.
The little boy does not understand:
- But why dad?
The father answers him:
- Your mother died 2 years ago son!
