I quite enjoy walking about at night (10-2am) just to clear my head before going to sleep, as strange as that may sound.
Bumping into people at night, at such a time, usually gets some funny reactions. Which I tend to escalate due to finding it hilarious.
I've noticed that pretty much every woman, if not all, tend to speed up significantly when they become aware someone's walking behind them.
Obviously I'm not going to be outrun by some woman, so I'll speed up a little too. And you can just notice the panic that's going through their mind. Completely irrational, and slightly offensive in thinking I would harm them, but most of all just rather entertaining.
Men are even more entertaining. Especially when sitting inside a parked car. Just making eye-contact makes them immediately look away followed by the obvious 'click' of the doorlocks. While I do drive around with doors locked, I have never done so as a reaction to a single or multiple person. It seems ridiculous to me.
The stupidity in all of it though, is the false sense of security and irrational thinking that triggers their reactions. What makes a woman think she could possibly outrun me if I had wanted something from her? Or what safety would a locked door provide for a man that gets scared via eye-contact? The fact of the matter is, that if I wanted, I would have. And there isn't a damn thing you could do about it unless you had a weapon of sorts with significant stopping power.
Yet here we are, I'm just stretching my legs whilst listening to
R.E.M. - Uberlin, intensly happy, and here you are; on edge.
