Well, in this case, Captain-First Officer relationship :)
Data and Worf are filling in as Captain and First Officer (respectively) because Picard and Riker are off of the ship for an extended time. Before this scene, Worf had been a little huffy with Data on the bridge.
I thought it was a great explanation of how you shouldn't negate your spouse in front of others, and instead speak to him later, privately. Show your man that you respect him :) Especially when you're around others.
