Another Hattie-ism

In the car, Hattie likes to play I-Spy. Usually I'll just say, "I spy...," but she says, "I spy with my little eye..." So today I thought I would do it her way and I said, "I spy with my little eye..." Before I could finish that part, she interrupted me and said, "No, no Mom. You say, 'I spy with my big eye.'" I guess because I am a grown up I have to say "big" eye.
