Last week, my WAW mentioned during our last phone conversation that the tires on her car were defective. Today, I called a tire shop in her hometown (900 miles away from where I am), paid for a set of used tires, and left a voicemail on her phone for her to go get her tires replaced. I did it because I love my wife and I also love our 3 boys dearly.

Was this a good move or did I break a DB rule?
