What could be more natural, when invited by the King and Queen to tea, than to ask to bring a friend? And that, of course, is what the hero of "May I Bring a Friend?" does. Not only to tea, but to breakfast, lunch, dinner, apple pie and Halloween - one invitation for each of six days of the week. The King is most gracious. "Any friend of our friend is most welcome, " says he. And his graciousness extends to giraffes, lions, hippos, monkeys, all kinds of friends. Not all of whom are on their very best behavior. It must be assumed however, that everyone (including the reader) enjoyed the friends, for why else would the king and queen step off to the zoo for tea on the seventh day.
