This is the therory of Ottimathics
We discoverd this on several occassions whilst walking home from LUG meetings. Whether it matters from which meeting you are walking home from is still not clear as we only seem to have guide dogs enabled on such jaunts. It has a passing homage to Bistromathics.
Why Ottimathics? As a member of Malvern LUG, Ottis who used to guide (when he felt like it) Ian, was often involved in just such experiments. As he is now retired and enjoying the freedom where no 'Orange Guide Harness' is required, I thought it right that he should get a mention.
There are 2 versions the first involves guide dogs and the second is more general, although the first seems to make less sense it happens more often in that manner.
When walking down a road with a quide dog and his owner and you come to cross a road either coming in from the side or crossing over the road you are on, no matter what you do the quide dog always ends up in front and the rest of your party are shuffled around so that the sentence you began when you started crossing the road has no meaning when you finish it as the original intended recipient has been 'shuffled'
No matter what type of road is being crossed, the dog and owner will always, in a group, be the last to arrive at the crossing place, and the first to have completed that crossing, totally independant of the size of the group that they may be travelling with, or the direction in which the group thinks it's travelling.
Just to remind you what this law states in case you had forgotten.
