Somebody doesn't seem to tell the truth. If we are sure that it is not us who are doing the deceiving (for in that case; let's stop it and turn to honesty), we need to be on our guard for deceivers. Whenever we hear a story we do not completely believe, we need to ask ourselves who stands to benefit by the narrative that is presented. It might reveal the source and motivation of the story so we can make an informed decision if we believe it or not. And, the old saying 'if it seems to good to be true it usually is' can guide us as well. Let's not be fooled!
Don't just read the future; help create it!
