Return Poem by Ima Ryma

I heard a knocking at the door.
An elderly lady stood there.
I had never seen her before.
She just walked in without a care,
Saying that school that day was fine,
And was I visiting her Ma.
Her strange behavior was a sign
That perhaps I should call the law.
The cops came and took her away.
She has Alzheimer's I now know.
My house is where she used to stay
When just a child, decades ago.

I thought of my house as a kid.
Would I one day do as she did?
