Flutter tilted her head at the slightly smaller boy. "I have no idea. They kind of catch the wind and hold a pocket of it? I think. I don't know." She shrugged, her wings fluttering.
"Something to do with air pressure." Squeaky whispered. "It's higher underneath and lower on top and lifts the person, or the bird."
"How'd ya hear that, Squeaks?"
Squeaky glared at the taller girl. "How do you think?" She started shaking slightly, her response to fear.
"Oh, right, you lived in Doctor Thomas's pocket for a month. Literally." Flutter went to ruffle Squeaky's hair.
Squeaky, true to her name, squeaked, and shook her head, trying to banish memories of what she'd seen and heard. "I don't want to think about it!" she squeaked.
Flutter, realizing she was triggering a breakdown, hugged Squeaky tightly. "God, I'm sorry, Squeaky."
"It's okay. Can we just go get something to eat now?"
"Sure, I'll go flying to look for berries; you can stay on the ground and try to find some nuts and seeds?"
"Okay!"
