A client said "Some (readers) are really good. They can tell the future." I gave me my usual reply "The future is malleable. It changes when we change. The reading is based on the current situation which you or the other party can change." And I added "If I'm that good at reading the future, I wouldn't be an astrologer (for clients). I would spend my time on the lottery or betting on horses."
Note to self: do not talk about lotteries or betting on horses in the future.
