Can someone help annotate this poem? After the Disaster

By Abigail Deutsch
New York City, 2001

One night, not long after the disaster,

as our train was passing Astor,

the car door opened with a shudder

and a girl came flying down the aisle,

hair that looked to be all feathers

and a half-moon smile

making open air of our small car.

The crowd ignored her or they muttered

“Hey, excuse me” as they passed her

when the train had paused at Rector.

The specter crowed “Excuse me,” swiftly

turned, and ran back up the corridor,

then stopped for me.

We dove under the river.

She took my head between her fingers,

squeezing till the birds began to stir.

And then from out my eyes and ears

a flock came forth — I couldn’t think or hear

or breathe or see within that feather-world

so silently I thanked her.

Such things were common after the disaster.
