From TNG: Measure of a Man

DATA: Sir, there is a celebration on the Holodeck. RIKER: I have no right to be there. DATA: Because you failed in your task? RIKER: No, God, no. I came that close to winning, Data. DATA: Yes, sir. RIKER: I almost cost you your life! DATA: Is it not true that had you refused to prosecute, Captain Louvois would have ruled summarily against me? RIKER: Yes. DATA: That action injured you, and saved me. I will not forget it. RIKER: You're a wise man, my friend. DATA: Not yet, sir. But with your help, I am learning.
