something there is that doesn't love a wall.

Before I built a wall I'd ask to know
What I was walling in or walling out, 
And to whom I was like to give offence. 
Something there is that doesn't love a wall, 
That wants it down. --"Mending Wall," by Robert Frost

[Pieces of the Berlin Wall, Berlin, Germany]

[Peace Walls, Belfast, Northern Ireland]

 something there is that doesn't love a wall.
