When will people ever learn the word , no . I had work to do today and with the kids here , they decided it would be a good idea to answer the door before I could walk across the office to the living room front door . The lady at the door was selling a Kirby Carpet Shampooer and told me she wanted to do a Demo . I told her no . I had just shampooed my carpet and I had work .

Question: What led the speaker 's kids to open the door for the Kirby saleswoman ?
Answer: They are working with her and she agreed to give them a cut if the speaker bought oneThey had no idea they were doing anything wrong , they were just doing what they 'd been taughtThey knew the woman would annoy the speaker and were trying to be funny in a pushy wayNone of the above choices .
