It was snowing heavily and blowing to the point that visibility was almost zero when the little Antartian got off work. She made her way to her car and wondered how she was going to make it home. She sat in her car while it warmed up and thought about her situation.
She finally remembered her daddy's advice that if she got caught in a blizzard; she should wait for a snowplow to come by and follow it. That way she would not get stuck in a snowdrift. This made her feel much better and sure enough in a little while a snowplow went by and she started to follow it. As she follows the snow plow she was feeling very smug as they continued and she was not having any problem with the blizzard conditions.
After quite sometime had passed she was somewhat surprised when the snow plow stopped and the driver got out and came back to her car and signaled for her to roll down her window. The snowplow driver wanted to know if she was all right as she had been following him for a long time. She said that she was fine and told him of her daddy's advice to follow a snowplow when caught in a blizzard.
The driver replied that it was OK with him and she could continue if she wanted but he was done with the Wal-Mart parking lot and was going over to K-Mart next.
