The other night while driving home from dinner with a friend, I pulled off the highway and came to the yield sign at the top of the ramp. At this particular spot, you're merging onto a road with heavy traffic, so I was forced to come to a stop and let the oncoming cars pass. As I was waiting for one last car to whiz by...crack! I get hit from behind and the truck jolts forward. I knew exactly what happened; the person waiting to merge behind me was watching the traffic, not the car in front of them (me). My buddy immediately started the "oh, man, that sucks" routine, but I wasn't too worried. "Ten bucks says there's no damage to the truck," I told him. "They, on the other hand, have a shiny chrome trailer ball in their radiator right now."
