The note sits beside a bunch of flowers, written on pink paper in the script of a child.
"Dear little boy in heaven, my family feels very sorry for what happened yesterday at my school," it reads.
"I hope you are now in heaven without the pain you had yesterday. Rest in peace. Teresa."
It sits among a collection of flowers and cards that has been left by students, friends and teachers outside Carlingford Public School, in Sydney's north-west, where a six-year-old boy was struck by a car and died on the last day of term on Wednesday morning.
On Thursday, parents brought their children back to the school on the first day of their summer holidays to help them come to terms with what had happened.
Among the tributes were Christmas candy sticks hung on the steel fence and two stuffed teddy bears. A friendship chain made of red, green and white paper was strung on the fence.
Kindergarten student Zoe Stephen, 5, her sister Elle, 4, their Malaysian cousin Akshay, 6, and Akshay's 38-year-old mother were hit by a white Nissan Dualis outside the school.
Akshay was killed instantly, when he and Elle were pinned under the car.
Elle suffered a broken pelvis. Akshay's mother sustained a knee injury.
A mother from the school said she knew the driver of the car, but her family had been unreachable and "it was still too raw" to comment.
The woman's two daughters laid a bunch of light pink flowers on Thursday with two cards attached.
Written on one of the cards was: "Unfortunately everything has to come to an end, but staying calm and happy will make you feel better. Love Matilda."
Sister Imogen wrote: "Staying calm and staying happy is the best you can do and remember, I will always miss you."
The tragedy has touched others well outside the school community.
Sue Lee drove from Castle Hill with her boyfriend to lay some flowers. She said she did not have any children but the tragedy had affected her. Like Akshay and his family, she was born in Malaysia.
"We heard it on the news so my boyfriend and I decided to come at put flowers," Ms Lee said outside the school.
"It's so tragic and so close to Christmas."
Another couple with no connection to the school also stopped by the tribute site.
While their two children stayed in the car, the man and his wife stood at the school gates reading the cards left by students at the school.
The man said they were in the area and decided to stop by and "look at where the crash happened" after hearing the story on the news.
The principal of the school, Neil Hinton, declined to comment and said all inquiries should be directed to the Education Board.
