Fluttershy was not a good example of a pegasus. She knew that, and it didn’t entirely help that other ponies in Ponyville sometimes forgot that she was, in fact, a pegasus. She used her wings so little that it wasn’t uncommon that ponies would be startled when she opened them. Not that Fluttershy ever meant to startle anypony, as it could be startling.
Still, it surprised a lot of ponies on an infrequent basis that Fluttershy could, and actually did, fly. But Fluttershy didn’t fly like other pegasi. At least, not when she wasn’t fleeing from something. They flapped and flapped and pushed the air out of their way, and all of that sounded terribly exhausting to Fluttershy.
Fluttershy glided. She floated through the air, catching the thermals that rose from the buildings in Ponyville, only flapping her wings just enough to keep her from crashing. She was content to let the air take her on whatever tour of Ponyville and the surrounding farmland it cared to take her on. Up here, above the buildings but still below the usual clouds, here she could relax.
Here, she felt free, with the wind rustling through her feathers, her mane and tail streaming out behind her in a waterfall of pink, and she felt so at peace that she could almost, almost sing. For a short time, she floated above the constant fears and worries that fretted her so much, forgetting everything. She floated above the judgement, perceived and real, above the cries and cares of the world, and even momentarily forgetting that Twilight Sparkle was a princess now and she had a throne.
Here, she was at peace.
