If you are out walking ,out a message or what ever and you meet a complete stranger would you say hello ,good morning ,afternoon. Or presume they already knew that and just pass them without speaking .
Strange how dog-walkers always seem to 'open' and say hello, while joggers are 'closed', and pass by without even looking at you, let alone saying anything. Why is this?
Joggers may also have the earbuds of an MP3 player in. When exercising you tend to get yourself 'into the zone', it's the only way to tolerate the pain :)
I am too busy saying hellow to the people I do know
otherwise strangers
anyone with a dog gets a hello
and men with kids - as they usually are marshalling the troops and need encouragement
No women and no one under 21
as TWR ... talking to a woman unbidden is asking for trouble
I would add in kids
