A, the Quiet One, and the new one are here for a few hours. Since they arrived at lunchtime, we all sat at the table and ate. The Infanta was in her high chair, but since we only have one, the Quiet One was bouncing around, doing things on a regular chair fit to give me a heart attack.
At almost the end of the meal, the Infanta (who been listening to a chorus of this the whole time) said, "Quiet One* sit down!" When the Quiet One sat(!), the Infanta followed with "Thank you!"
*Herself actually used the real name here.
