New York is a very dangerous city----specially at night.Many people dare not going out alone to the streets after dark.This problem is even worse for a single woman like Miss green.As a singer, she had to drive home after the shows.She needed a "friend" when she drove to work and back home.She found a man-shaped ballon named Bob and set him on the passenger seat of her car while she drove at night.People on the street thought the woman-driver had a man with her so she felt safe.
