Analysis of I won't be home for Christmas

I won’t be home for Christmas,
just say a prayer for me,
that this thousand miles between us,
will not forever be.

No gleaming frosty winter,
no snowflakes in the air.
But there’s a chance of fireworks,
and rockets here or there.

I won’t be home for Christmas,
enjoy it there with them.
As you unwrap your presents,
remember where I am.

No bonfires full of chestnuts,
or carols in the air.
No choirs to serenade us,
just lonely desert prayers.

I won’t be home for christmas,
no toast of wine or beer.
So as you pour your glasses,
raise one for us out here.

Don’t let my absence hinder,
you from enjoying life.
Soon we will toast together,
If I come home alive.

I won’t be home for Christmas,
I’ll miss the New Year too.
But once my time here passes,
I’ll make up for it soon.

If I return as normal,
I’ll pick up where we left.
If I become immortal,
just know I did my best.

I won’t be home for Christmas,
please say a prayer for me,
Whatever fate hurls at us,
won’t sever you and me.

…however long that may be.
