Sniff Out The Meaning

I just asked Emily if she could sneak upstairs and listen outside Katrina's door to see if she is awake. She comes over to me and says, "Is this how you sneak?" and wrinkles up her nose and sniffs. I look and her with a confused look, and so she repeats the motion and the question. Light bulb for mom, "No, that's sniffing, sneaking means very quietly without running or shouting." "Oh, ok," and off she goes. A few seconds later she comes back. "I don't hear any noise, it's very quiet." Little moments like these just give me the giggles. I wonder how many times I've told her she was sneaky and she thought I meant she smelled bad or something. :)
