Josef K and Beryl B were deep in discussion about forward and backward movement

Beryl maintained that a car could only travel backwards and forwards on independent occasions and would never be able to travel in both directions at the same time

Josef disputed this and noted that of one placed a car on a spoon and if the spoon was moved backwards whilst the car was being driven forwards then the car would be able to move in both directions simultaneously

As hard as she tried Beryl was unable to disprove Josef’s theory so they agreed to differ
