Walk
For my sake
Close to that wall
Keep close as you move down the street
And when you come to the corner
Pause
Wait.

Then
If after a while you see no one
Look around for another wall to keep close to
Because you must go on.

If
At first
You don't see any
Wait.

Wait and do not be afraid.
Walls are always there for those who need them.

I don't know why --
Perhaps I do. You see
We build them as we go.
You see
It's the only way we can keep on going.
