i guess the next question is of those 33 recorded instances (or 41.25 possible instances), how many people were around the two of them? if they were literally standing within arms reach of each other, but also within arms reach of a dozen other people, it may not be that interesting if they never connected. but if they were within 5 meters of each other, and there weren't anyone else within a 100 meters of the two of them, that would have been a pretty awful missed connection.
