Books of my childhood.
The wall between my computer desk and the porch is lined with bookshelves. And also piles and piles of paper that doesn't fit in the filing cabinet and books that don't fit on the shelves. The bookcase nearest the porch door has children's and young adult books on it. Whenever I go sit outside I grab one to read. Yesterday and today I read snippets of Harriet the Spy. I've probably read it a thousand times, all told, and it just keeps getting better. But I am still mad that Harriet never gets to finish playing Town.
