MonoMonday - Walls

We don't need no education
We don't need no thought control
No dark sarcasm in the classroom
Teachers leave them kids alone
Hey! teachers! leave the kids alone!
All in all you're just another brick in the wall.
All in all you're just another brick in the wall.
Pink Floyd

Today's MonoMonday theme is inspired by that classic Pink Floyd song - Another Brick in the Wall. It seems there are many interpretations to the meaning of these words but Roger Waters apparently wrote this song as a rebellion against the schooling he experienced in the 50's. 
The concept of the album was to explore the "walls" people put up to protect themselves", as Waters did.  "Any time something bad happens, we withdraw further, putting up "another brick in the wall."
Here is my interpretation of the song with another brick that just happened to be waiting in the centre to be put in the wall.
Thanks to GoranZebuhr for his excellent song based themes this month.
