Early in the outbreak, the school served as a temporary shelter, and an elderly resident from the requester's home helped serve meals in its kitchen. The day the horde broke into the school, everyone fled in a hurry, and the elder's hearing aid was left behind in the kitchen. Since then they can barely hear anything; a few days ago zombies lingered outside the door while they were alone on the ground floor, and they never noticed. You need to go to the school kitchen, find the hearing aid, and send it back by drone.
