Spock: You have an efficient intellect, superior physical skills, no emotional impediments. There are Vulcans who aspire all their lives to achieve what you’ve been given by design.

Data: Hm. – You are half Human?

Spock: Yes.

Data: Yet you have chosen a Vulcan way of life?

Spock: I have.

Data: In effect, you have abandoned what I have sought all my life.

Data: Ambassador Spock, may I ask a personal question?

Spock: Please.

Data: As you examine your life, do you find you have missed your humanity? Spock: I have no regrets.

Data: “No regrets”. That is a human expression.

Spock: Yes… Fascinating.
