It's a humorous, gentle, but spirited look at a little boy's world, and I'll nominate the father for a Great Fictional Father award. For those of you who can't deal with it, I should probably mention that the father in this book puffs on his pipe while they're having this little chat. Otherwise, I can't see anything anyone's likely to find objectionable.
"And you'll be a wonderful little boy, too."
Chris giggled. "How did you know I wasn't very nice today?" he asked.
His father turned out the light in the hall. "Alexander told me," he said.
While we're on the subject, if you know of another Great Fictional Father in a book for younger children, please feel free to drop a note in the comments.
