Given the task definition and input, reply with output. In this task, you will be shown an extract from a movie plot. You need to read the extract and create questions that can be answered from the extract. Once you create a question you also need to provide the correct answer for it. Write your answer like "Question: your question, Answer: your answer". The questions should be well-formed and grammatically correct. The questions should be completely answerable from the given passage and should not require any external knowledge. Subjective questions are not allowed. Short answers containing words that are present in the passage are preferred. Create questions that result in factoid answers. A simple rule of thumb to decide whether a question is a factoid or not is to see if two different people with average reading/comprehension skills would come up with the same answer after reading the passage.

In 1961, an unpopular boy named Harold leaves a Valentine's Day card at the home of Susan Jeremy. Susan and her friend David mock and crumple up the card, prompting an enraged Harold to break into the house, and kill David by hanging him from a hatstand.Nineteen years later, Susan is divorced, has a daughter, and a new boyfriend named Jack. On Valentine's Day, Susan has Jack take her to a hospital to pick up test results, and on the way into the building, she is observed from a window by a man in surgical garb. The man strokes a photograph of a young Susan, and sabotages the elevator Susan boards in order to delay her while he kills the doctor who has her paperwork, which the murderer tampers with. A janitor finds the doctor's body, and has his face dunked into a sink full of acid by the killer.While looking for the doctor, Susan coerces a friendly intern named Harry into getting her results, which Harry notices are abnormal, prompting him to bring them and Susan to Doctor Saxon. The peculiarities of Susan's paperwork (which the murderer further sabotages after killing a pair of laboratory workers) cause Doctors Saxon and Beam to order that she be detained for observation. Harry uncovers evidence suggesting that someone is pulling a "con job" on Susan, but he disappears after promising Susan he will straighten things out. Jack, who had fallen asleep in his car while waiting for Susan, enters the hospital to look for her, and is lured to an empty room, where he is decapitated. The killer places a box containing Jack's head in Susan's room, then replaces it with a cake (identical to one seen in the intro) when Susan goes in search of aid.After Susan tells him about Harry's findings, Saxon goes to look over the copies of her paperwork in the archives, where he is murdered with an axe, an act witnessed by Susan. Susan's claims of there being a killer on the loose are disbelieved, and she is strapped to a gurney after being deemed delirious. The staff prepare to perform emergency surgery on Susan, but are killed in rapid succession by the murderer, who takes Susan to a vacant operating room. Susan pulls off the killer's mask to reveal he is Harry, who is really Harold. When Susan asks what he wants, Harold responds, "What I've always wanted. Your heart".Before Harold can cut her open, Susan stabs him, and escapes. Susan is pursued to the roof by the wounded Harold, who she sets on fire, and sends plummeting onto the street below. The next day, Susan is released, and reunites with her daughter and ex-husband outside of the hospital.
