A cоnstructiоn cоmpаny wаs removing аir conditioning equipment from a truck parked on a residential street, using a crane. The equipment weighed several hundred pounds. A half-block away, the mother of a seven-year-old boy was standing on her front porch, watching her son walk to the school bus stop at the end of the block. As the boy walked past the construction site, the air conditioning equipment fell, landing mere inches away from the boy, who calmly continued walking to his bus. While the boy suffered no ill effects from the incident, the boy's mother, who had a clear view of the incident, immediately fainted after seeing her son so close to certain death. For the next 48 hours, the mother was unable to function due to shock over the event. In the following months, the mother had difficulty sleeping due to nightmares as a result of the incident. The mother sued the construction company on behalf of her son for negligent infliction of emotional distress, and produced evidence at trial conclusively establishing that the construction company was negligent in allowing the air conditioning equipment to fall. Which of the following is the construction company's best defense against this action?
