Wall

On a summer day, weighty
With heat, air
Moved only by the wings of 
Impervious dragon flies,
You taught me to build
A wall out of large
And irregular slabs of
Slate, grey and crusted white
With age, using
Cement mixed thick and clumpy.
The work was more intellectual
Than I had imagined, the pieces
Fitting together like an awkward
Puzzle. The progress was slow,
Steady and satisfying.
Now I build towers and
Walls and walkways of words,
Lessons learned.
To this day that first wall
Leans up hill and is
Still standing.
