Sherlock Holmes knew the difference between seeing and observing. In one of the best-known conversations between Holmes and his friend Dr. Watson, Holmes chided Watson for not knowing how many steps led from the hall up to their rooms at 221B Baker Street. “You have not observed,” the detective told the doctor. “And yet you have seen.” Maybe it isn’t all that important to know how many steps are in a staircase – and so we can forgive Dr. Watson for his ignorance. But what happens when the thing that is seen but not observed isn’t an inanimate object like a flight of stairs, but a human being? Ask Linda Loman. She knew.
