Tough Guy

We were Christmas shopping, and a little boy (about four years old) was in a nearby shopping cart with his grandma. The boy must've said something like, "Look at that little kid," because before I could stop him, Miles hit the ground running and was over at his cart. Here's the conversation that ensued:

Miles: "I'm not a little kid - I'm a big kid! You're a little kid! You're a little kiddy-kid!!"

Other Boy (perplexed): "What's your name?"

Miles (chin as high as he can hold it [i.e., about three feet off the ground]): "Miles Smif."

Other Boy: "How old are you?"

Miles: "Nufin."
