Passage 2
John liked to wear his hair very long. Some of his friends thought that it
looked like a girl's hair, but they never made jokes about it, because
John was a big, strong young man, and he did not think jokes about his
hair funny.

John always went to the barber's twice a month to have his hair cut and
washed, and one day the barber said to him, "Now why don't you let me cut
most of this hair off and make your head tidy? Nobody would recognize you
if I did that, I am sure."

John said nothing for a few seconds, and then he said, "Perhaps you are
right -- but I am sure that nobody would recognize you either if you did
that to my hair."
