A mother of a five-year-old child was outraged after finding a nursery rhyme dictating a lockdown procedure taped to a chalkboard at a school she was contemplating sending her daughter to.

Georgy Cohen has shared an image of the nursery rhyme online, and it has quickly gone viral. The piece of poetry is meant to be sung to the tune of "Twinkle Twinkle Little Star," replacing the innocence of its source material with a unfortunately useful set of precautionary tactics. Limericks like "Shut the lights off say no more. Go behind the desk and hide. Wait until it's safe inside," prompted Cohen to declare that "this should not be hanging in my soon-to-be kindergartner's classroom." 

The concerned mother is not angry with the school, and is happy with the way they are taking the necessary steps to educate their students on how to handle a lockdown scenario. Instead, she is upset that the widespread instances of gun violence plaguing American educational institutions have made such nursery rhymes a mandatory in childhood classrooms.
