A psychic goes into an opticians to get his contact lenses replaced.
Upon learning his customers profession, the optician asks what next year has in hold for him.
The psychic replies “Alas, I cannot tell you”
The optician, who has had a terrible year up to this point, begs him for just a basic reading, even offering free contact lenses for a year.
“As I said” the psychic retorts “There is nothing I can do.”
The optician, getting desperate at this point, offers his services for free for life.
The psychic, getting annoyed replies “I wish I could, however if I had 2020 vision, I wouldn’t be going to an optician in the first place!”
