Slightly off Madison windows. Maybe you should use a window sill as a bookshelf, especially if your window is at street level and people look in all the time. Face the spines inward, and no one will know what you're reading, but they will know that you are a book-reader ... or at least a book-user.
But this other window really disturbs me, not because I'm wasting any time worrying about people getting tattoos. I'm worried to find myself living in a world where people get tattoos in places that display gnomes in the window. (Is tattooing a step in a profit-making scheme that includes stealing underpants?)
