The neighbor boy came over to play with KJ (4 y/o) they were laying train tracks and KJ said, "Mom help me, it's stuck" so I got down there and fixed it. Neighbor boy says, "Thank you" then KJ said, "Thank you, thank you Susan." (my real name) It just took me by surprise, that's the first time he's ever done that. Then he said, "Oh am I supposed to call you mom?" All three of us laughed.
