A mother in the US has shared a picture from a kindergarten classroom, with instructions for a lockdown drill to the tune of Twinkle Twinkle Little Star.
Georgy Cohen was touring the kindergarten for her daughter when she spotted the rhyme shared the image on Twitter.
Lock the door
Shut the lights of
Say no more
Go behind the desk and hide
Wait until it’s safe inside
It’s all done
Now it’s time to have some fun!
Do you think this is morbid, or necessary?
