A kid's guide to why we should all share. Sharing is unnatural -- but it can be learned. Kids start out so beautifully. The whole world is theirs. Until someone else wants part of it, too. Or, until they see something they can't have. That's when things start to change. Learning to share takes time, and sometimes a special book. This is a book your kids won't want to read. Read it to them anyway. Probably more than once.
