Lawndale, North Carolina (CNN) - It's before sunrise, and the janitor at Burns High School has already been down the length of a hallway, cleaning and sweeping classrooms before the day begins.
This particular janitor is painstakingly methodical, even as she administers a mental quiz on an upcoming test. Her name is Dawn Loggins, a straight-A senior at the very school she cleans.
On this day, she maneuvers a long-handled push broom between rows of desks. She stops to pick up a hardened, chewed piece of gum. "This annoys me, because there's a trash can right here," she says.
The worst, she says, is snuff cans in urinals. "It's just rude and pointless."
With her long, straight dark blonde hair and black-rimmed glasses, Dawn looks a bit like Avril Lavigne. But her life is a far cry from that of a privileged pop star.
She was homeless at the start of the school year, abandoned by her drug-abusing parents. The teachers and others in town pitched in - donating clothes and providing medical and dental care. She got the janitorial job through a school workforce assistance program.
