CHICAGO When Shari Hart was diagnosed with leukemia last week, her 14-year-old son wanted to do something special.

So, this past weekend he wrote her a simple message: HI MOM, with a smiley face inside the O.

Two simple words that had a big impact, because of the effort it took. Her son, Will, didn t simply write those words in a text message or on a greeting card, he wrote it in giant letters in the snow on the roof of the parking garage across the street from his mom s room at Rush University Medical Center.

Later, with the help of his dad, Will added a few more words: GOD BLESS U.

Shari, 48, is at Rush for about a month for chemotherapy for acute myeloid leukemia. Five simple words from her son and husband went a long way to lifting her spirits, given the way the words were delivered.

Anyone who came in the room, I said, Look what my son did! It was such a proud thing. And then to have my husband gone down and say, Let s put a little more on ... who thinks this? My family, apparently, she said. It just gives me true joy, and lifts me up. So when you re feeling a little low, just some simple words, God bless you, made me cry.
