For Magritte (on a rainy day)
This is not an umbrella.
But when is a poem
not an umbrella?
Why, when it’s raining
of course!
At other times a poem
is always an umbrella,
ready to give shelter
within its papery embrace.
And though its body may be thin
at our touch it will begin
to open out into new
worlds of possibility.
Provided, of course,
it is not raining.
