When I was a kid in about the second grade, the school picnic was down along the river. Out of desperation, I used nettles (didn't have any sagebrush). That was a bad decision.
One time nearly 25 years ago, my wife and I were ranching south of town. We arrived home from church about 1 p.m. one Sunday, and were driving through our heavy cows before we had dinner. An airplane circled overhead, and then landed out on a small meadow east of our house. We drove over to see why the plane landed, and it was a neighbor and his wife. We made small talk very briefly, and the neighbor asked me, "Could you drive me over to that stackyard? I've got to go real bad." Of course, I did, and our wives stayed at the plane and visited. I felt bad later for even arriving at the scene. The last thing in the world my friend wanted, was "company" showing up when he landed. If we had not come along, he could have just stepped in behind the plane, performed his deed, and he and his wife could have been on their way.
Close to fifty years ago, an old neighbor was mowing hay one day with an IHC H tractor and single bar mower. He felt Nature's call, and as his tractor was not in the habit of starting real well, he left it running as he crouched alongside one of the tires. Unfortunately, he hadn't looked behind him, and he didn't hear a car drive up because of the noise of his tractor running. His visitors were a couple Iowa cattle buyers and their wives. There was nothing to do but say "howdy" and I'm not sure if they shook hands. He parked his tractor on a hill before shutting it off, so it could be rolled down later to start. He got in the car with the Iowans, and they proceeded to go look at the nice Hereford yearling steers that he had for sale.
