In addition to providing shade, lumber, fruit, and oxygen, trees are also a great place to read a book. If you're ever bored, or in need of a quiet place, find a book. Then find a tree. Then climb the tree. (This last step is complicated if you have a book in your hand. Perhaps get a friend, who will pass you your book once you are secure in the tree.) Then read the book. The only disturbances you will encounter are squirrels (inconsequential) and/or bug (annoying).
NOTE: Reading in trees might result in broken bones (if you fall out of the tree), broken books (if you drop your book into a pile of nasty leaves), and/or dirty clothes (if the tree hasn't been washed recently). The author takes no responsibility for these and/or other damages incurred while reading in a tree.
