From USPS News Link:
Manahawkin, NJ, Letter Carrier Dean Pantis had grown accustomed to seeing an 82-year-old customer on her porch whenever he delivered her mail.
Pantis was worried, then, one day recently when the woman wasn’t there, so he called out to her through an open window to see if she was OK.
The customer replied that she’d fallen and needed help, and she directed him to a spare key hidden outside.
The Postal Service employee soon discovered that the woman had tripped over an electrical cord in her bedroom — leaving her stranded overnight.
Pantis got the customer up and into a chair, called her daughter and remained on the scene until she arrived to provide further assistance.
