We will never turn to salt

Do you remember?
That serene day in winter?
We spent it on the beach,
Ice cream filling our mouths.
You devoured strawberry
And I stuck with mint.
Our hats kept us warm
And our scarves choked our breath.
We walked for such a while.
I decided to turn and look back.
That distant ice cream truck
Was a speck against the sky.
And seemed to me, alone.
