Four walls . . .
The same four walls every day.
The same four walls greet each day.
To relieve the sameness
Except when the ’phone rings
Except the fax with work to be done.
Change is needed for stimulaion
A new voice
Lasts only a few minutes
And is gone without being seen.
To prevent creeping stagnation.
Four walls, no change:
All is stagnant.
