This conversation happened today.
While Cadance was wearing two different tutus at the same time.
And while she was running laps around her play room.
C: Princess Cadance
M: You look more like ballerina Cadance
C: No, princess Cadance
C: Mom is not a princess
M: What, I can't be a princess
C: Mom has no skirt
M: I think princesses can wear pants
C: No, I have a skirt (actually a tutu), tutu, and another skirt
6 months ago Cadance hadn't even heard the word princess; she is now apparently an expert
