Alyssa Hacker was shopping in Target with her 18-month-old son, Owen, when they met an older gentleman. Then, the man did something incredibly kind, and bought Owen $20 worth of stuffed dinosaurs. He explained that he'd lost his own young grandson the week before. Alyssa posted the story on Facebook, where it went viral. She's grateful for the man's kindness, and glad that her son could be a ray of sunshine to others. As for Owen, he loves dinosaurs even more!
