Even an exhausting battle with leukemia wouldn't stop Ralph Duquette from walking his daughter Heather down the aisle on her wedding day.

Long bouts of chemotherapy, falling blind in one eye and being in a coma for five days had left Ralph very frail. But he was determine to be at his daughter's wedding on October 10th in Maine, and to walk her down the aisle.

He worked with physical therapists all summer, and his goal was just to walk a few steps. Instead, he stood up and walked his daughter all the way down the aisle. Not only that, but he performed the ceremony and danced with her at the reception.

I don't usually cry at wedding videos, but man...the feels.
