Lion or Lamb?

People often ask where I get the ideas for my stories, and there’s an easy answer when it comes to In Like a Lion Out Like a Lamb: I grew up with this phrase about March. The reverse was also supposed to be true, if March comes in like a lamb it will go out like a lion. I came up with the idea of writing a picture book because I heard a librarian say she was looking for a book on that well-known phrase and couldn’t find one. I happen to love weather, everything about it, so I thought immediately, “That’s a book I should write!” And I did. Speaking of which— is there some book you have been looking for that you wish someone would write?
