I had some trouble helping Sage get dressed, because I didn't do a good enough job of convincing her that she had actually picked out the matching clothes I'd picked out for her.
Sage: "It's my day today, so we're going to do what I want."
Eric: "Whoa! I, me, mine."
Sage: "I'm not being mean."
Eric: "No, you're not being mean, but you are acting a little self-centered."
Sage: "I'm not acting self-centered!"
She then put on her princess tiara and stomped out of the room.
