The Wall

The last time I checked, you were rubble. 
I know because I took you apart. 
So why the hell are you standing again? 
How do you always manage to rebuild? 
And stronger each time, too? 

I will set to re-dismantling you, of course. 
There's little else I can do. 
But one of these days 
When it all gets too much 
I might just smash myself against you.
