Georgia Mom Tara Wood was grocery shopping with her 4-year-old daughter Norah when the young girl hopped up in the cart and shouted, “Hi, old person!” at a man passing by.

“Before I could tell Norah, ‘Please use kind words,’ the man stopped and said, ‘Well, hi little lady! How are you today?’ ” Wood tells PEOPLE.

Norah and the man, 82-year-old Dan Peterson, chatted for a few minutes and then went their separate ways. Then Norah asked her mom if she could take a picture with her new friend.
