As psychics deal with HERE and NOW, no absolute predictions can be made.
All is possible - All IS.
A psychic embraces a part of the Flow, and through the psychic reading the psychic sorts out the possibilities and offers the one reality the psychic finds most probable in relation to the current reality.
Thus, the flaw of prediction:
If a person chooses to lock him/herself into the perceived reality offered by the psychic reading - the person pushes away choices.
There are no absolute predictions.
