Data: Lieutenant, I am dissatisfied with your performance as First Officer. 

Worf: May I ask in what way? 

Data: You continually question my orders in front of the crew. I do not believe this is appropriate behaviour. 

Worf: With all due respect, sir, I have always felt free to voice my opinions even when they differ from those of Captain Picard or Commander Riker. 

Data: That is true. But in those situations, you were acting as Head of Security, not as First Officer. The primary role of the second in command is to carry out the decisions of the Captain in this case, me. 

Worf: But is it not my duty to offer you alternatives? 

Data: Yes. But once I have made a decision, it is your job to carry it out regardless of how you may personally feel. Any further objections should be given to me in private, not in front of the crew. I do not recall Commander Riker ever publicly showing irritation with his Captain as you did a moment ago. 

Worf: No, sir. 

Data: If you do not feel capable of carrying out this role, I will assign it to Commander La Forge and return you to Tactical. I would not enter it into your record as a reprimand, simply as a transfer. 

Worf: I would prefer to remain at my current post. 

Data: Then I expect you to conform to the guidelines I have laid out. 

Worf: Aye, sir. 

Data: Dismissed. Mister Worf, I am sorry if I have ended our friendship. 

Worf: Sir, it is I who has jeopardised our friendship, not you. If you will overlook this incident, I would like to continue to consider you my friend.

Data: I would like that as well. 

Worf: Thank you, sir.
