The picture shows villages A to K and all but one of the lanes between them. The missing lane does not cross any other lane.
I remember that it is possible to reach a friend’s village by starting at my village, going for a walk along the lanes, and using every lane exactly once.
I also remember that it is possible to start at my village, go for a walk along the lanes, and pass though each of the other villages exactly once before returning to my own village.
Which two villages are joined by the lane which was missed out of the picture?
