One day one of the girls in her class said to her, " Miss Smith,why does a man's hair become gray before his mustache and beard do?"
Mary laughed and answered, "I don't know, Helen. why does it become gray before his mustache and beard do?"
" I don't know either, Miss Smith," answered Helen, "but it happened to my father." The other children in the class laughed when they heard this.
