As told on Reddit, Jessica Hickey's father has been waiting for this moment for a long time. She's his only child, and her mother died 20 years ago. Understandably, he's been asking for grandchildren since Hickey's wedding night.
At a restaurant, with the camera rolling, Hickey reveals with a pacifier that his wish will finally be granted in November. When he realizes he's going to be a grandfather, his reaction is surprised, happy and tearful. In a word, priceless.
