Wait! I say. Daisy looks up, her tail wagging. This tells me that she is prepared to wait. First, I carry the treat just a few steps. I am wondering how much suspense she can take. Sometimes, I get as far as the door; sometimes, just out of sight. But I am always full of misgiving. Daisy has swapped this tiniest of treats (and look! it’s all dry and broken!) for a mere sound. She’s traded it. I repeat my instruction. I try to be kind. I tell her that every word is held as a promise. Daisy’s wagging intensifies; she is tracking the slightest movement of my hand. Don’t  worry! I say as gently as I can. It’s all going to mean something soon.
