Ever try to talk about Jesus, explain your Christian point of view, or do things the way you do to someone who isn't a Jesus follower?
One of my favorite scenes from Star Trek IV:
McCoy: Perhaps, we could cover a little philosophical ground. Life. [pause] Death. [pause] Life. [pause] Things of that nature.
Spock: I did not have time on Vulcan to review the philosophical disciplines.
McCoy: C'mon, Spock, it's me, McCoy. You really have gone where no man's gone before. Can't you tell me what it felt like?
Spock: It would be impossible to discuss the subject without a common frame-of-reference.
McCoy: You're joking!
Spock: A joke [pause] is a story with a humorous climax.
McCoy: You mean I have to die to discuss your insights on death?
Spock: Forgive me, Doctor. I am receiving a number of distress calls.
McCoy: I don't doubt it.
