I walk into the kitchen this morning, ready for a nice hot cup of coffee to start my day. My wife is standing at the stove, singing along to a song on the radio as she cooks breakfast. I smile at her, delighted to see her in such a good mood this early in the morning. As I approach her, she turns around and gives me a quick kiss on the cheek. "Morning, love," she says. "I've got some hot coffee waiting for you."
