G3, and others.
Two vehicles parked in the roadway, conversing, is NOT unusal or antagonistic, in many places around the country. In many rural areas, in fact, we call such a practice a business meeting. Those familiar with the area and customs just drive around the parked vehicles. I may be wrong, BUT if such an incident happened in rural areas that I'm familar with all across this country, it would be considered normal.
And, in those same areas, if someone not familiar with the area and practice where to pull up behind those parked vehicles and start laying on the horn, and especially if that person started yelling abusively... The BOYS that were talking in the road might just point a gun, or even come over and pull the horn blower out of the car to give some instruction in country manners and customs. Just a guess...
Rural customs and manners are USUALLY foreign to those from urban areas and the urbanite can find himself severely chastised for rudeness in some rural locals.
Not a sermon, just a thought.
