I walk home from evening meetings quite often at around 9pm-ish. Nice quiet residential area, about a 20 minute walk, street lights, a few passing cars and dog walkers so I don't really feel vulnerable. Until, that is, I hear the sound of someone running up behind me and think panic, shit, this is it. And then it turns out to be some thoughtless twatty jogger who doesn't have the cop to think that maybe running up behind a solitary female on a dark street isn't the most thoughtful thing they could possibly do. I want to trip the next one up, or push them into the road or do something equally twatty. Cross the road, fuckwits, so you don't scare the shit out of lone pedestrians.
