Let us take a step back from the absurdity of this situation and consider how much time Chi has spent with her face in the ground thus far. On second thought, let's not. There's only so much embarrassment a girl can take.
Here is what happens - she picks herself off the ground; the feather has, as many fluffy things do, attached itself to her shirt. She debates with incredible sincerity whether the tradeoff of having a distinctly aromatic feather in a direct vector from her nose is worth the struggle of physical contact with it, and eventually comes to a utilitarian conclusion - the ends justify the means. The beleaguered feather puts up a heroic resistance before being inelegantly removed and banished from her line of sight. As it flutters quietly to the ground, it lets out a silent cry at its cruel mistreatment.
Chi, preening as though she'd just won a confrontation with the final boss, distinctly ignores it. She also distinctly ignores the lingering voice in the back of her mind that is making fun of her for essentially bullying an inanimate object and taking pride in it. Sometimes, you have to take your victories where you can.
(i lost track of where i was going with all of this ;w;)
