One day a girl went for a walk on a sunny day. Her name was Jesica. She saw a sign that said 6 Miles to the next city. Jesica thought that she will walk that distance and wisit the next city. So she walked and walked and after 6 miles there was no city.
She kept walking and reached that city after 9 Miles. When she ask people in the city, why that sign said 6 Miles, the people smiled and told her, that the 6 was a 9 that was sitting up side down.
Then Jesica had much fun with the people in that city.
