Lookover Lane divides two rows of houses. Each house on one side of the lane is directly
opposite a house on the other side of the lane. The houses are numbered consecutively 1, 2, 3,
and so on along one side. Once the end of that side of the lane is reached, the consecutive
numbering continues at the house on the other side of the street opposite house number 1. The
consecutive numbering continues along this second side until the last house is numbered. When
the residents of house number 37 look directly across the lane, they see the house numbered 84.
