The cat reminds her of "rinka" , and the teacher wonders if the cat is a stray. The teacher asks the cat if he is wearing a collar and the cat responds that he is not wearing one, but a collar that says "him." The teacher wonders why the cat does not have a collar, and when the cat replies that he does not wear one, the teacher responds that it is because he is a teacher, and she does not know anything about him
