After a 10th grade student from Falcon High School in Colorado passed away suddenly, two men were photographed outside the school holding signs saying "you are loved".
The school has sadly also lost four staff members in recent months, as well as two other students, according to Fox 21.
The single act of kindness and suppport left people stunned.
They left their thanks on Facebook:
The person behind the signs also apparently sent a message claiming responsibility, and offering support to any student who would like to talk about their feelings.
