In regards to the last post: I really do feel sorry for the driver who almost hit me, but in a man-that-really-sucks kind of way. This is not to say that I am not very grateful that he didn't hit me.
A word about personal safety from another angle. Expectations regarding personal safety seem to be another West/East Coast cultural difference. In DC, I try to be as careful as I reasonable can. I rarely walk alone at night, even to the grocery store that is just a block away. When we moved into our current house, I asked Andrew to install locks on all the windows, even though we live on the second floor. This was around the time that some guy was sneaking into homes and cuddling up to women asleep in their beds, even (in one case) when her boyfriend was asleep beside her. Add the fact that my county has almost legendary car theft rates and a not too shabby number of murders, and it just behooves one to be careful.
Here, I live in a house that doesn't have locks. Well, the front door has a lock, but no one has a key to it, so the front door is always left open. They leave their laptops in the living room (although I notice all the bikes have locks) and no one seems worried that their stuff is going to get up and go walking. This freaked me out when I first got here. My solution has been two pronged: I took all my equipment to the university as soon as possible, where it is all safely locked up, and each night I tie my door shut. I haven't told my flatmates about that second one, because I'm sure they'd think I'm crazy, but I can't sleep if I'm worried about the crazies that might wander in.
