If you see a cars indicator (turn signal for you over the pond lot) blinking and you assume the car is likely to be turning in that direction very very soon now (in WT parlance) then if he doesnt you were at fault for misreading his indications, not him for leaving them on or getting his left and right mixed up.
It's the same big J and his indications, except he doesnt exist and any indications are born of fertile imaginations and indoctrinations of men to believe in such things.
Indications is the get out of jail free card for blame mitigation.
