It has nothing to do with foreigners were talking about the old timeers when you would walk by a shop in a village or drive by a nice country village and there would be people for example farmers or local people out doing their shopping would wave at you driveing by which i thought was really very nice as i never expericened it before as i am not from the country but when i use to go on holiday down in the country i really thought it was beautiful the way people say hello or just wave at you when driveing by but that seems to have changed its a pity sad really but the new generation sadly will never replace the old generation
