This incident occurred with me while teaching at the nursery school.
Once when I was at school and was about to begin the class and start teaching, one of the kids’ living in his own make-believe world, suddenly announced that he was Simba, the Lion.
I pretended to be frightened and asked him. “So where’s your tail?” “In my diaper,” he replied. The whole class had a ‘laughing burst out’ including me.
