She instantly realized there was an emergency: The man was being swarmed by hornets.
Hough rushed to his aid, dispersing the insects and guiding him to safety.
The Postal Service employee called 911 and comforted the customer until paramedics arrived and took him to a hospital, where he was treated for around 50 stings.
The man told Hough he prayed for someone to find him and when he opened his eyes, she was there.
He later visited the local Post Office to give her a card.
“Thank you,” he wrote. “God used you to save my life.”
