« All alone, or in two's,
The ones who really love you
Walk up and down outside the wall.
Some hand in hand
And some gathered together in bands.
The bleeding hearts and artists
Make their stand.

And when they've given you their all
Some stagger and fall, after all it's not easy
Banging your heart against some mad bugger's wall. »
- Roger Waters (Pink Floyd, The Wall, 1979)
