All too often I read statements from others on this forum that they never answer a knock at the door, appear with gun in hand if they do, and suspect anyone and everyone who feels they have reason to "trespass" on said person's precious property.
Get a grip, folks--answer the dang doorbell. It might be for you!
Coming home at 12:30 am last night after an uneventful late shift, I drove through a particularly dark section of my neighborhood street and almost slammed into a Ford Ranger sitting crossways in the middle of the street. Dark night, dark street, dark truck=close call. The vehicle had obviously rolled down the sloped driveway and into the road. No lights were on in the house, and none came on when I leaned on the horn a bit.
Knowing someone would hit the truck if I simply did the easy thing and drove on, I parked and rang the doorbell. That's right--at 12:30 am. I stepped back to the edge of the porch, hoping whoever came to the door wasn't one of those who can't take an unarmed breath.
A sleepy-eyed man opened the door (unarmed as far as I could tell). He didn't seem upset, fearful, or alarmed (maybe the uniform and badge on the belt helped), and I apologised for waking him but thought he'd like to know his truck was sitting in the middle of the street. In so many words, he said he forgot to set the blankety-blank brake and thanked me for waking him.
I had never spoken to this fellow before. That's what good neighbors do.
For those of you who refuse to respond to unannounced doorbells, maybe the sound of crunching metal will inspire you to rise, arm yourself to fend off those zombies you're so worried about, and see if you forgot to set the brake! Maybe your neighbors aren't so good as to risk getting shot to save your car.
As for me, I've answered doorbells and frantic pounding in the wee hours twice, both times for neighbors with an emergency. Neither time did I think I had to shoot anyone.
That's what good neighbors do.
