I’ve been repeating this thought exercise because people seem to have a hard time delineating when blame goes the other way.
Bob is standing next to a bomb, and a fuse is sparking down. Jill, on the other side of a fence and reliant on Bob, lifts a huge very expensive sign for Bob to stamp out the fuse. Bob does not stamp out the fuse, bomb goes off.
Who is at fault; Bob for not stamping out the fuse, or Jill for not getting a high-amp bullhorn to inform Bob he should stamp the fuse?
Feel free to vary the analogy, but the question would extend to: When does it become Bob’s fault that he didn’t take action?
