Red sweater

A girl decides to emigrate, but her suitcase won’t close. She takes out the sweater her grandmother knitted for her. As she does, the yarn gets caught in the zipper of the suitcase and follows her all the way to the airport.
The yarn repeatedly tangles around her leg, as if trying to dissuade her from leaving, but the girl doesn’t give up. In the end, the plane takes off. The sweater is completely unraveled, and its yarn trails out of the airplane door, floating in the air.
