Runners, joggers, walkers, when do you look?
When you are engaged in you favored activity and see someone similarly engaged coming from the opposite direction, at approximately what distance do you make eye contact?
Do you look away or avert your eyes, finding something else more interesting until they are at the proper distance or do you look at them until they acknowledge your existence?
When you finally do look at them, are they looking at you or do they look up to meet your eyes only after you look?
Have you ever had someone, or do you ever, completely ignore the oncoming person?
