Something lost, something found

I belong to a small, bimonthly writing group with two poets. Many of the writing exercises we do are not really poetry-specific, but the last two times we have met I have written poems. Today's exercise was to write about something that meant something to us, but which had been lost. Here's mine. It is about loss and resilience.

When Singularity was eight years old
We scooted to school.
Schuss rattle rattle, schuss rattle rattle.

One day I left his helmet on the playground.
An oversight. An accident. A mistake.

Somebody took it.

THEY STOLE IT ON PURPOSE!
I WILL KILL THEM!

Singularity
Could not comprehend.
They took it,
But not from him.

From him, helmet stolen.
From me, scooter riding with my treasured boy 

Purloined.

Thieved. 

Pilfered.

Helmet replaced, but not the same.
No schuss. No rattle.

Months pass. 

And then one day
As I scooted away alone
I heard

“Mom, I want to come with you!”

Schuss rattle rattle, schuss rattle rattle,
Even though we never saw that helmet again.
