UPDATE: The family who wrote the message has been found. See their story here.
A nurse at Rush University Medical Center thought she saw people playing in the snow on a parking garage ramp, but what they were actually doing turned out to be much more heartfelt.
Angela Washek, a surgical intensive care unit nurse at the Chicago hospital, said she saw four people on the garage's roof at 1 a.m. Monday and quickly realized they were writing a message.
“Hi Mom, God bless U,” the message read, with a smiley face in the letter “O” of Mom.
A photo of the snow-stamped note was posted to the hospital’s official Twitter account Monday, and was also sent to NBC Chicago.
Hospital officials aren’t sure which patient the heartwarming message was intended for or who wrote it.
“We don’t know who though and would love to find out,” said Deb Song, associate director of media relations for the hospital.
While the message writers remain a mystery, one thing is certain—the snowy note put a smile on more than one face.
