My wife really hates the cold.
With a couple days of colder weather lately, she's been dropping hints that we (meaning ME) should re-light the coal stove. Well, I spent several hours working outside yesterday and when I came back I found that she had re-lit the stove! No guidance from me, no questions. Just did it.
She even went down to the basement, re-filled the coal buckets and brought them back upstairs. I was more than a little shocked, but genuinely impressed. And she's happy with the warmth. When momma's happy, everybody's happy.
