Evil Trucks:

In my (relative) youth, I used to bicycle to and from work in the evening. Work was 3.4 miles from home, reached via either a high speed road with no sidewalks, or a parallel rural road (with no sidewalks). I preferred the rural road due to the almost total lack of traffic and dogs. There was a terrific hill on this road. One night I was pushing my way uphill home at about 2:00 A.M. when I heard a sound behind me: the loud, grinding motor sound of Evil Trucks.
Now I want to be perfectly clear about this: there was no doubt in my mind, there were several trucks coming uphill behind me and THEY WERE EVIL! I cycled as fast as I could to a turnoff, ducked into the bushes, and waited, heart pounding, while about four construction vehicles drove slowly by.
I waited until the sound of them had vanished ahead of me, and then proceeded after them. I did NOT want to catch up to them. After awhile I crested the hill. I could again hear the trucks. They had stopped next to a newly-built low income housing development. I wanted to turn around and go back, but that meant another six miles of biking at least. Instead I put my head down and zoomed past the evil trucks – and their evil people – as fast as I could. I was afraid they would try to stop me, but they didn’t.

At home, I could think of only one thing: why had I KNOWN they were evil? Why did my heart pound in fear? What was I afraid of? I thought a lot harder about this issue a week later, when I learned that the people in these trucks had come to steal a very expensive, very heavy water pump from in front of the low income housing development. It was actually too bad I’d been afraid to look at them. But now I knew: THEY WERE EVIL! How had I known that from the first? I cudgeled my brain, and I think I know the answer.
If the truckers were going to a big construction site to do something in the morning, they should have been on the parallel state road. Since they were on the rural road, they HAD to be going to a local site. What construction crew, what batch of heavy trucks, has to BE somewhere in a small town in the middle of the night? If a water main had broken in the middle of town, they would STILL have approached it via the state road.
I knew they were evil, because I knew at once that they had no good reason to be on the rural road.
