Godfrey then confronted the teenager, who was still at the skate park.
"I started trying to explain to the boy that my son was trying to make friends with him but because he has a throat tumour he can't talk clearly and with his autism he doesn't communicate very well," she said.

But the teenager told her he had anger problems and then punched her hard in the face.
"Thomson Park is the problem spot. It needs to be opened up more, some of the trees pulled back a bit and some lighting and cameras," she said.
Since posting on Facebook about the attack, Godfrey received more than 50 messages of support, including from several people saying they had had experienced similar bullying and intimidation at the park.
"Thomson Park is our local, we shouldn't have to feel intimidated to go there. A lot of people won't even go there because they feel intimidated," she said.
