Proper Poise

"Now remember, just because you aren't really a pony doesn't mean you can't learn proper poise."
"... Is this better?"
"Marginally. But don't fold your ears down, it makes you look weak. A proper prince needs to appear strong to his subjects. A proper princess needs to appear graceful and radiant. And you need to work on both, Quasimodo."

MORE QUASIMODO QUARTZ STUFF
Quartz and her siblings have a governess that has been training them on their royal etiquette and posture; Gold Standard. She teaches them individually every week or two, but she teaches all three together by the end of the four sessions. While Royal Beauty is perfect at it, Skyla is too flighty and doesn't sit still, and Quartz is too nervous to look regal. But Skyla isn't usually scolded, her flaws get her only a quick reprimand. Quartz, on the other hand, gets reprimanded more harshly. She isn't tortured or punished, she just gets a more rude lecture compared to the others.  During the class together, her reprimands are less harsh towards Quartz, although there's always a hint of bitterness.
The pony in the wheelchair is Prince(ss) Quasimodo Quartz, Shining Armor and Chrysalis's foal/nymph hybrid. She has a tumblr which has finally returned after technical difficulties.
