[Sam is next to me while I get my computer out. On the desktop, he spots the picture in the last post.]
Sam: "Mommy, why did you call that picture 'Sam and Lily and Charlie?'"
me: "Because it's of Sam and Lily and Charlie."
Sam: "But you're not supposed to have two 'ands.' It's supposed to go, 'Sam, Lily, and Charlie.'"
me: "OMG, did you just correct my grammar?!"
Sam: "I don't know what that is. I just know you did it wrong."
