The school girl who wrote a letter asking whether having autism makes her "bad".

“I was born autism but that doesn’t mean I was born bad,” she wrote.

Seven-year-old Cadence has an intellect and way with words that belies her years.

She was also born with autism, and this week she used her written abilities to express exactly what it’s like to be a child with the neurological disorder.

In a heartbreaking letter to her mum, the Queensland girl asked her mother whether “being autism” made her “bad,” reflecting on the negative stereotypes perpetuated by recent news reports about people on the autism spectrum disorder.

“Grownups always say it is hard being mum or dad if your kid is autism [sic] and it said on the TV if your autism [sic] you hurt people,” she wrote.

She added, “kids who have autism have to be put in a gale [sic] to keep others safe”.

The Year 1 girl then expressed beautifully how her own experiences of living with autism had not been reflected in those negative media reports.

“I don’t like hurting people. I don’t like being scared. I would be scared in a gail room [sic],” she reflected.

“I was born autism but that doesn’t mean I was born bad.”

At the end of the letter, she asks her mother: “are you crying?”

Her mother’s handwritten response reads: “Yes. I have happy years that you know what is true; and I have sad tears because there are lots of people who don’t know what is true.”

Since being posted online on Wednesday, the poignant letter has been shared more than 740 times and liked almost 500 times.

This is not the first time Cadence’s writing skills have made headlines.

In August, an essay she wrote was published by Kidspot and dubbed “the year 1 essay that stopped us in our tracks”.

She wrote in that essay: “Autism is why I’m different.  Its why I don’t talk. Its why I get scared of people. Its why I like to know things before they happen. Its why I like sharp pencils. Its why I like mummy cuddles. Its why I get sad at parties.

“It might be why I’m clever but my brain might have just been born clever just like it was born Autism. My hair was born blonde. I am Cadence. I am just me.”

On a Facebook page set up by her family, the girl’s mother Angela explains that Cadence’s keen observational skills helped her

“Cadence’s sensory differences means she hears, sees and observes every detail around her – every conversation, every sight, every smell; as many autistic children do,” she said.
