Prepositions sit next to Now, saying: Get help, we're running out. Look back, it was better and worse over there. Down the road is an edgy cliff. Future and Past, identified without article, insist: We are what made you. You don't exist. Who's ever heard of a space without measure? The Present winks and whispers: Wait for me and I won't appear. Think of me and I'll leave you. Obsess over me and lose your time.
