“Did I want him to act? Or would I prefer a lifetime of longing provided we both kept this little Ping-Pong game going: not knowing, not-not-knowing, not-not-not-knowing? Just be quiet, say nothing, and if you can't say "yes," don't say "no," say "later." Is this why people say "maybe" when they mean "yes," but hope you'll think it's "no" when all they really mean is, Please, just ask me once more, and once more after that?”
