River prefers to move rather then stay still, even if it's only slight or slow movements. Staying still reminds her to much of The Academy when she was kept in a sleep like state most of the time and unable to move around of her own free will and she hates being reminded of that horrible place.
|You are the dancing queen, young and sweet, only seventeen
Dancing queen, feel the beat from the tambourine
You can dance, you can jive, having the time of your life
See that girl, watch that scene, diggin' the dancing queen.|
