Watered Down

As a woman was about to go home from a long and stressful day at the
office, her cell phone rang. It was her husband.

"Will you be joining me in the whirlpool bath tonight?" he asked.

"What a lovely way to spend an evening," she thought.

She was about to tell him how considerate he was when he continued,
"because if you're not, I need to start adding more water to the tub."
