"#IfIDieInASchoolShooting is trending and that is the sad reality of America."
Lane Murdock tweeted this response to the tens of thousands of people - many of which children - using the hashtag on Twitter.
Some of them want their families to know what to do with their bodies after their deaths. Others would like their deaths to be used to encourage gun reform.
The hashtag has been used more than 45,000 on Twitter in the past 24 hours.
'I'll never be able to see my sister again'
Andrew Schneidawind was the first to tweet #IfIDieInASchoolShooting after the recent shooting at a school in Santa Fe, Texas, that left at least 10 dead.
A week earlier he had visited Marjory Stoneman Douglas High School - the site of the shooting that left 17 dead in February 2018.
I'm gonna try and get a hashtag trending called #IfIdieInASchoolShooting. If you wanna join, feel free. #IfIdieInASchoolShooting I will never be able to finish my animated TV series, I'll never be able to see my sister again, and I will have to become a martyr. #NeverAgain— Andrew Schneidawind (@SoldierSchnyd) May 20, 2018
While he said he was happy that the hashtag resonated with other students in the US, he said it "really shouldn't have had to".
"Us kids should not have to write what we will lose and miss because of our leaders' inaction," he wrote on Twitter. "Hopefully this shames them".
For Emma Gonzalez, who became a prominent activist after February's Parkland, Florida, high school shooting, the hashtag was an opportunity to remember her friend Carmen Schentrup who was killed.
'I will only become a statistic'
Thousands of young people shared the things that they would miss out on if a shooting happened at their school.
#IfIdieInASchoolShooting I will never get married or be a mother, My 7 siblings would lose their baby sister, I will never experience a life out of highschool. I would want everyone to keep my memory alive by pushing for gun reform.— noelle devoy (@noelledevoyy) May 20, 2018
Others reflected on the loved ones they would leave behind.

I will leave behind...
-an autistic brother who needs his sister.
-A mother with multiple sclerosis who needs help with her IVs, etc.
-A father who told me I could be anything in the world.
-A grandmother who took me in after both my parents couldn’t. https://t.co/c9XDGufpWM

Many thousands of young people used the hashtag to call for the reform of gun control legislation.
#IfIdieInASchoolShooting I will never get to see gun control and common sense gun laws be placed. I will never see the day that law enforcement wakes up and does something.— Allie💘 (@officiallymex) May 20, 2018

While the conversation played out among young people, some urged "grown-ups" to pay attention to the fears of "children in America".
Hey, grown-ups. Children are tweeting under #IfIDieInASchoolShooting. Take a look.— Sandra Steingraber (@ssteingraber1) May 20, 2018
Some want their bodies dropped off @NRA headquarters. Many want their deaths politicized. They have eulogy suggestions and funeral preferences.
Children in America.
