Tara Wood's daughter Norah, 4, saw an elderly man in a supermarket and stopped to talk to him while she was buying cupcakes for her birthday.  “Hi old person, it's my birthday,” said Norah. Then she asked her mom to take a picture of her and Mr. Dan, the elderly man she just met. The two had a short but lively conversation. Tara then posted the picture on her Facebook page and some of her friends recognized Mr. Dan and told her that his wife had died in March and the moment he spend with her daughter talking in a supermarket was the happiest he'd been since. A couple of days later, Tara called him and took him for lunch with Norah. The two became close.
