If you have an autistic kid, this book may very well be for you. I adore the way it spells out how friends greet each other and introduce each other, what they do together, what it means to be a friend and what friends DON'T do.

There aren't very words per page, but those words can be somewhat larger, so I'm thinking this would be a good read-aloud book for younger kids and then something early elementary kids can read to themselves. (Assuming average reading abilities, everyone is different.)

A good book to share one-on-one with a child--little details make it too much for a group read. By observing humans, an alien explains to an alien audience about human friendships. What sorts of things do friends talk about? What sorts of things do friends do to get along well together? What sorts of things can lead to conflict in friendships (being bossy or selfish, breaking promises, being untrustworthy, etc)? What helps to end the conflict (admitting mistakes: with examples, apologizing: with examples)? What are some different kinds of friends (casual, activity, close, long-distance)? A good, practical guide that should be really helpful for kids who don't automatically grok friendship.
