The Eruv

Running through the boroughs of London is an invisible line.
A line suspended between electricity poles and shady trees,
between Victorian façades and faceless chain stores.
A line running through pathways and highways, amusement parks
and parking lots, the grey asphalt and the grass.
A line cutting the azure sky and the rain, the spring blossoms
and the howling wintry wind.
An imperceptible line flying high above passers by,
and yet silently touching the lives of many.
