Subtle Differences

So we are about to start the goodnight show for the kids' bedtime wind-down, when Sean says "Mom, where is my milk?". Lori is outside getting the dogs to come in, so Carter says to him "I will get it for you, Sean." She brings it to him as he's watching the show, and he distractedly mumbles to her, "Thank you, mommy". To which Carter replies "I'm not Mom, silly." So just to keep it going, I say to her "Are you sure? You look like Mom to me!". She looks at me and says "No....I'm not Mom. I have a different shirt!" As though she thinks that the only way that I can tell my daughter and my wife apart is by their wardrobes. So cute!
