In the space of 2.28 miles, I experienced a) an attempt to chat me up and b) a near miss.

I thought I'd go out for a short ride this morning before getting started on things for school. I got out, and the street I live on was crawling with cars--somewhat unusual for a Saturday. Turns out there was some kind of high school band event that was using our campus. I made it to the stop sign at the end of the street, and noticed that my computer wasn't working. Usually that just means the magnet's slipped--quick and easy fix, so I made my way to the first available driveway and then to the sidewalk next to it. This happened to be near the art school building. I was fiddling with the magnet when an art student (I'm pretty sure--none of the students from my uni are ever over there) came up to me and asked if I wanted some help. And he kept talking. I wasn't paying much attention to what he was saying, just that he was making me uncomfortable. I quickly thanked him for his offer to help and got the heck out of there.

My second loop around the area (creepy art student was gone), I was approaching the intersection next to the museum. It's Y-shaped, and the left "twig" of the Y has a stop sign, while the trunk and right "twig" are continuous and don't have a stop. There's also a pedestrian crosswalk across it. There are also a load of parked cars on the right side of the street. I was in the lane (no choice if you don't want to get doored) but most drivers are used to seeing cyclists in the area, so it's really not a big deal. I approached the intersection and slowed enough to check for pedestrians, checked the other "twig" and noticed a car stopped at the sign. "Okay," I think. "Since I'm traffic, I can quite happily continue and he can wait for a gap like a normal person." So I enter the intersection.
Apparently this guy was not a normal person. Either a) he was really impatient, b)he figured "Oh, it's a bike. It can't be going faster than 5 mph...I think I can beat it." or c)He interpreted my checking for pedestrians as letting him through. He turned left in front of me.
I don't know what it was, but something had told me he was going to try something like that. I braked, hard. He realized his mistake and stopped. I could have reached out and touched the rear passenger window. Luckily, the car behind me had seen what was going on and stopped. I let the first car go, not wanting to cause too much trouble, and the woman behind me was nice enough to let me ride off first.
I called it a day after that.
