I've had a couple recently.
1: A few weeks ago I was on the last mile, heading home from a really nice 40 mile ride after work. I was on one of my hometowns straightest, levelest roads that passes the local elementary school. Just as I'm passing the playground with about a dozen kids playing, a garbage truck runs a stop sign and almost hits me. I slowed down and looked back to see he's yelling at me. I stop and realize he thinks I did something wrong. We start yelling at each other, lots of profanity (from both of us, sadly). I started to roll back towards him but thought better of this action. He pulls away and as I slowly start riding away I apologize profusely to the 2 mothers or teachers sitting there that witnessed the entire thing. I felt bad for my actions but they seemed more concerned that I wasn't hit.
2: This morning my buddy meets me at 7:30 for ride. 5 miles in I notice a white Explorer come down a side street, they can go right, left or straight. I thought he was going to turn left, thus putting him right beside me, going in the same direction. And as they start to pull out I thought that's exactly what's happening. Nope, they're going straight...straight into me! They missed me, about 2 feet, no big deal. My buddy comes up and he's angry. I asked how close they got, he said if I would've tapped my break I would've been under their tire. Great way to get the blood flowing early in the morning.
