“Hi Mom, God Bless U!” was written in the snow and could be seen from multiple hospital rooms.
According to a hospital staff member, the photo was taken from room 1155 at the hospital.
WGN-TV reports the message was stamped out in the snow by 14-year-old Will Hart, whose mother, Shari Hart, has been staying on the 14th floor of the hospital as she battles Acute Myloid Leukemia, a cancer of the blood.
Last weekend, Will called his mother and asked her to look out the window of her hospital room for a surprise.
“I just wanted to say hi to my mom and say, I love you,” Will said.
One Rush employee said “It reminds us of what we fight for everyday as healthcare workers. We fight for the families of our patients just as much as we fight for the lives of our patients. No matter how cold it gets, there is always a message of warmth if we just open our eyes to see it.”
