At the crack of dawn, five high school seniors set out to shovel snow from the driveway of a New Jersey woman so she could drive to her lifesaving dialysis treatment. On Sunday night, the forecast for the following morning was showing up to eight inches of snow, which was dangerous news for Natalie Blair, who, according to CNN, had a dialysis appointment she couldn’t miss. Her neighbor, Brian Lanigan, used to be the person shoveling Blair’s driveway, but when the storm was expected to start he was due at work as an EMT.

So Lanigan turned to his little brother, Patrick, for a huge favor: help shovel Blair’s driveway before the sun rises and clear a snow-free path for her to get out the door. The teen put out feelers for other help, and his friends and fellow Parsippany High School classmates Justin, Chris, Tyler and Amon said yes to the call. The five boys bundled up and then to headed over to Blair’s house at 4:30 a.m.

Thanks to great teamwork, the group was reportedly able to get the job done in only about half an hour, and Blair made it to her dialysis appointment. The teens didn’t get a snow day, but their school did give them a delayed opening. The boys all slept at the Lanigan house and rested up for a full day of classes later on.

Later that day, Patrick’s father, Peter Lanigan, shared a photo of the boys, which has now won the hearts of an entire community and beyond.

All of the accolades were amazing to the younger Lanigan, but his dad told CNN that the incredible act was not unusual for the teen. He called his son a “small kid with a big heart,” and told the outlet that Patrick is an active church member and a “peer buddy” in his community, helping students on the autism spectrum.
