Who am I now?

Who am I when I'm
All alone
When my sister is away
My children gone
My husband about his chores
And the holiday bustle
Vanishes into silence
Like a passenger train
Pulling out of the station
Loud with fanfare
"All aboard!"
Then rushing away into
The countryside
Since Mom died I am
No longer a daughter
This stillness so rare
I will wonder here
A bit longer
