On our private road the Fed Ex and UPS drivers USED TO speed down it!! There is only our home and one other home on the private road. No injuries ever happened but I could see it coming. I talked to the UPS driver and asked him to really slow it down. He is more local, and did slow down a great deal. The Fed Ex driver was some kind of Arab foreigner and didn't seem to understand or care. This Fed Ex driver also tore up some of my property one time too. Anyway, I waited for the next speeding Fed Ex delivery to my neighbors, farther up the private road. I then took matters into my own hands, so to speak, and on his way out of the private road, all of a sudden this Fed Ex driver got TWO flat tires! I was surprised it wasn't four, but I settled for two. Old barbed wire clips on the dirt roads can be a common thing in the country.... if you're not careful!!
As he sat there with two flats, I never said a word, and I never offered help of any kind, which is very unlike me. He kept staring at me and I at him, but nothing was ever said. He got the message apparently, because he now goes rather slow down our private road, keeping children, dogs, calves, etc., safe from his pathetic, unsafe, driving habits!
Kind of like that old story about the 2X4 and the mule!! Sometimes you just have to get their attentiuon and let them understand you are serious!
I am very sorry about your brother's dog!! Being a dog person myself, I can only imagine your pain right now!
