(CNN)Rebecca Field is furious. She didn't sign up for this.
The Richmond, Virginia, teacher signed up to teach art history -- not, as she says, to "be ripped apart by a spray of bullets that came from a semi-automatic rifle."
Make no mistake, she'd give her life to save her students. But she resents that we live in a time when that's a choice teachers now have to make.
So Field wrote an open letter to elected officials; a powerful letter where she pours out her heart about the way things are, and her frustration at why they are this way:
At the end of my teaching contract, it says that I will perform 'other duties to be assigned.' I do not interpret these words 'as bleeding to death on the floor of my classroom.'
A responsibility too great
Field told CNN she was compelled to write the letter, and post it on Medium, after she read about Scott Beigel, a geography teacher at Marjory Stoneman Douglas High School who was shot and killed as he held the door open for students to escape.
I imagine that if someone was trying to kill my students, that I would try to save them with all my being. I probably would jump on top of a child to save her life. And yes, I might be one of those heroic teachers that the media writes tributes to after their death.
But she adds:
Instead of making dead teachers into saints, make them safer when they are still alive.
There are many things that irk her. Teachers are already underpaid and overworked. They are tasked with the awesome task of raising the next generation of responsible Americans. And they do it gladly.
"When you read these articles, you see these people as heroes. But we never signed up or volunteered to die," she told CNN.
She says she's terrified of the responsibility she and others like her are being asked to accept -- a responsibility "far greater than I can rationally accept."
On Back to School Night, I look out at the gazes of the parents in front of me as we silently make a pact. "I am giving you the most precious part of me with the knowledge that you will shield my child's body with your own when the need arises." They say this with their eyes. I agree to this responsibility and make a silent unbreakable oath before them.
As I am telling them about the 20,000 years of global art history that I will be teaching their child, I am also agreeing to die.
A choice too difficult
She shouldn't have to make such a choice, Field said -- especially since it means choosing between being a teacher and a parent. If she gives her life for her students, she robs her children of their mother.
How dare you force me to choose between my own children and those that I teach. How dare you allow powerful adults who love guns to be more important than a generation of children growing up in fear. I don't want to spend mornings memorizing my children's clothing so I can identify them later.
The September 11, 2001, attacks occurred during her first year of teaching. The safety drills have become more intense.
"A shooting at work is something that is always in the back of my mind," she said. "But as a parent I worry more about my children -- the fear that something might happen to them, or how will they grow up without me in their lives."
A solution too elusive
Field wrote the letter last week. This week brought President Trump's suggestion that one way to ensure school safety is to arm teachers.
How would that even work, Field asked?
