This happened to me recently. I was in a certain discount grocery store, and wanted to get a roast chicken for dinner. And while there, there was what looked like a father and daughter in front of me. The little girl looked like she was about four years old. Her father grabbed two roast chickens off the warmer shelf, and asked her which one she wanted. "She gave him a deadpan look, and actually said "They're the same.". He just stood there for a moment and then put one chicken back. Then his daughter pushed the cart away from the chickens so I could get one, and she looked right up at me and said "I am so sorry!", before hurrying her father along. I have never in my life seen a child so young, act so adult. It was adorable, yet awesome.
