It took about a half century to achieve but I’ve pretty much discouraged people from talking to me before 9-10 in the morning. For damn sure I’ve got them to expect snarling, grumbling and cursing at best and thrown objects or half coherent threats of horrible and imminent doom being more likely.Sometimes my wife tries talking to me in the morning before my left eye is even open. Granted, sometimes that takes 3 cups of coffee first, but still.
My lovely wife grasps the situation perfectly and doesn’t even try. She puts a large black coffee in front of me and leaves me alone. Anything that needs to be discussed she writes on a note on the fridge so I can actually comprehend post coffee.
Works great.
