My dad is a tree
(Book)

"It’s easy to be a tree. Just pretend your arms are branches, your body is a trunk, and your legs are roots. Don’t move, even if a bird makes a nest on your head, a squirrel hides an acorn in your pocket, and a spider builds a web under your arm. It’s OK: Trees don’t mind those things. Or so says the little girl who persuades her father to be a tree all day long, no matter what, even in the rain!" --publisher's website.
