Walls of Life

Be careful of the wall
It is delicate when new
One wrong move to take a brick down
Even step by step
Can result in a brick landing on you
Take care when building
Use concrete - renowned for its solidifying
Nurture your wall day by day
It will grow to be strong
But be warned
Sometimes walls prevent
The entering of something precious
Allow the bricks be taken down bit by bit
Don't chisel too soon
Lest they should harm
The careful dismantler
Are you inside looking out
Or outside looking in
Walls can be helpful
But they can hinder
Know when it needs to be taken down
Brick by brick
Don't let the bricks fall out and hurt
Just as it takes time to build a wall
It takes a moment to knock it down
With one adept, careful move
