The cattle have waited for me at the North Pond Pasture gate for two days in a row. They have grazed North Pasture for the past eight days, and now want to move on. They ignore me when they are happy. When they want to move on, they let me know by rushing ahead and assembling close to the gate they want opening. If I ignore them, they talk to me in low plaintive moos. If I walk through the gate and not let them through, they respond with longer, more urgent plaintive mooing. Cattle are not dumb animals, they just want us to think they are.
