You went to your friend, Kafka to show the new jacket you got. But as you were showing the jacket off, a loose button fell off.

"Oh no, did they not sew it on properly?"

She asks, taking your arm where the jacket sleeve's button was on.

"Let me fix it, I know how to sew."

She says calmly, looking on the floor to find the loose button but she shrugs it off, tearing one of her own jacket's button and sewing it onto your jacket's sleeve.

Its weird though, she values her jacket highly and never would like to have them ruined.
