Thank you mqqn for acknowledging the man at your door!
Rang a door bell once at a rural home, it was around midnight, I could see and hear that the TV inside was on & when I rung the bell, some lights went on, others went off, in response to my ringing. After 2 to 3 minutes and no reply I began knocking loudly. after waitiing for a few more moments and no one came to door or responded in any way, I started to verbally and loudly plead my case, you see, I was there in response to having discovered a very seriously injured, bloody and wet man who had slid his car upside down and into a creek, he had pulled himself out of the mostly submerged car through a broken side window and was sitting up leaning against a fence post when the headlight from my motorcycle revealed him to me. I eventually began screaming an abbreviated version of this to the people or person In the house begging them to call the police and request an ambulance. the residents never responded and I rode my bike down to the next rural home where the folks were Christian and helpful, answered my pleas and phoned the emergency crews. I returned to the injured man ( a bloody mess and loosing more blood rapidly thru numerous places, and waited for the ambulance. When the county police arrived, they were actually responding to 2 calls, one was for a report of traffic accident with injury's (this one, reported by house #2) and the other call was for a hopped up lunatic screaming in the front of a house, (me at house #1). I was 18 then, I'm 57 now and ever since, I never blow off or ignore those that are in need of help no matter the time of day. I lived for 15 years on a busy rural blacktop road where my house was the only visible lighted building for about 2 mile stretch if that road, in that time I had been approached at all times of day or night at least once a year by strangers, some scruffy, some yuppy, some white and some not. In no case did I turn away any of these people, usually they just needed gasoline, sometimes just to make a phone call to help with a broken down vehicle and yes, a few times well after dark, they were just LOST. Typically, if in the wee hours the door bell was rung, yes, I would answer while armed (visibly) but that experience when I was 18, of the folks who would not answer the door, always prompted me to try to help.
Caution is always prudent no doubt,
(maybe the folks that would not answer the door many years before had no gun to help them confront there fear.)
Oh, yeah...the injured guy... I went to the hospital to check on him and give him his wallet that I found on the ground after I watched the wrecker pull that car from the creek, he survived, and I met his wife and two little girls.
