High school seniors shovel neighbor's driveway at 4:30 a.m. so she could make it to her dialysis

(CNN- )When the weather forecast called for up to eight inches of snow in their New Jersey community, brothers Brian and Patrick Lanigan immediately thought of their neighbor Natalie Blair.

She depends on dialysis treatments -- and that meant the snowstorm could be a life or death situation.

Brian, who works as a local EMT, had shoveled the Blair family's driveway during a storm just a few days earlier, but he knew this time he would be on the job when the snowstorm struck.

It was up to his little brother Patrick to ensure their neighbor would be able to leave her house for the treatment she desperately needs.
