Magnetic Levitation

Rush hour.
Jam packed MRT.
But everyone's arranged in a well-packed manner.

Even if doors open on either side at various stations, people in the carriage tend to be aligned in a certain fashion. Sort of like magnetic dipoles... but then once more space opens up they space out automatically. Personal space good, yes? Especially when you have people all around you and you're trying to see if you can align yourself in such a fashion as to maximise that extra few mm of space so you don't get sued for outrage of modesty. So people naturally try and stagger their positions horizontally, until it looks very much like the levels of dermis, and people slipping out twist their bodies in a graceful fluid dance not unlike the conditioning chemicals in some Pantene advertisement. At least this way you're not breathing down someone's neck. (Of course i'm not worried about anyone breathing down MY neck, i'm so tall!)

Can you tell? I forgot to bring a book today.
