Gloria Brett says her son, 46-year-old Darrin Brett, is "happy-go-lucky."
Darrin remains at Duke University Hospital in the Intensive Care Unit where he's being kept in a medically induced coma.
"His eyes are open, but he doesn't know who's talking to him," Gloria explained.
She says her son went to the library Tuesday to use the internet and apply for jobs.
"That morning he left the house and I told him, I said, 'Have a good day,'" she recalled. "I said, 'Be careful and everything and he says OK mom."
Darrin was hit and run over moments after parking his moped.
"The policeman told us that it was a pretty bad accident," Gloria said recalling when officers showed up at her home.
She gets emotional as she talks about her son. She says he suffered serious head trauma, has several broken ribs and is on a ventilator.
"I never seen him like this before, you know, it's hard," she said.
The driver of the car that struck Darrin told ABC11 Eyewitness News she hit the accelerator instead of the brake. Her family said the woman was on several prescription drugs.
Gloria wants to know why she was allowed to drive and why she hasn't been charged.
"She did something wrong and she should, she should suffer," Gloria said. "I'm suffering for it, my son is suffering, [and] his family's suffering. It's just heartbreaking to go in there and not be able to say I love you and have him play games with you and say I love you back."
Gloria says her son didn't have health insurance. She hopes the person responsible will pay for her son's care.
