Light Causes Shadows

I have taken to walking the city at night,
Skipping through the shadows of other people's lives
Until my edges become blurred.

Their lights burn brighter than mine:
No low energy bulbs in their illuminated squares,
But something more beating.

I watch their televisions through the glass,
Become a hanger-on at their parties,
And let their intimate moments play out silently before me.

I walk until my feet start to bleed,
Finding lives to try on for size,
Become them for the blink of an eye.

It's not safe to be out so late
Without anyone knowing where I am,
But surely they can sense my breath in the darkness?
