Disappointment was not something she should be feeling right now. Not an appropriate emotion at all. Embarrassment, yes. Go with that one. Oh, and shame. Don't forget shame.
She scooted back into a corner, trying to sit modestly by using her knees and arms to cover bits. "We should try not t'touch things," she said, her voice wavering a little. "Like coats," she added quickly. Argh.
She wondered if the coats that disappeared would come back when their clothes did. They should... Unless their clothes didn't actually come back and they had to find new clothes. And then what were they supposed to do? Trial and error? There wouldn't be any coats left by the time they were done.
