Oversights

It must be tough to edit,
Searching calmly for mistakes,
Whether spelling or grammatical,
That every author makes.

Still, it bothers me when reading
And some errors have slipped by,
Causing me to wonder, how much
Did this edit-person try?

First an idiom I noticed –
“Chock it up” instead of “chalk.”
Just to clarify, I Googled;
I was justified to balk.

Next, a character is asked,
At someone’s house, to shed his shoes.
Yet, upon a piano’s pedals,
Those same sneakers he does use.

You might think it’s nits I’m picking
But such errors hit a nerve
For the oversights of editors
We readers don’t deserve.
