Interpretation of a poem

The poem:
Names
Be mindful of names, They'll etch themselves
like daily specials on the window glass
in a delible medium. They'll pass
transformed, erased, cloud the wind dissolves
above the ruckus of the the under-twelves
on the slide, the toddlers on the grass,
the ragged skinny guy taking a piss
in the bushes, a marton tanning her calves
on a bench, skirt tucked around her knees.
A sparrow lands in the japonica;
as if it were a signal, all at once
massed pigeons rush up from adjacent trees,
wingbeats intrusive and symphonic-a
near-total silence is the clear response.

This poem is talking about how there is a name for everything no matter what it is.
It's using images to show that everything has a name, from the kids playing in
the park to the guy whizzing in the bushes. It doesn't exactly talk about names
and what they do, but it shows how they are used in the world around us.
