Not long ago I fractured my shoulder and needed surgery. After the operation, my husband of 30 years did all the things a loving spouse would be expected to do: He fluffed my pillows and put toothpaste on my toothbrush (try doing that with one arm!) and overlooked my crankiness.
My husband also helped me in ways so fundamental to our status as a married couple that I barely registered them. When I was loopy after the operation, he spoke with the surgeon on my behalf; he signed me out when I was discharged; health insurance through his employer covered my medical expenses.
