[Tucker is trying to persuade Kov to contact his father, who is dying. After failing with the direct approach, he tells Kov instead about a girl he once had a crush on]

Commander Charles 'Trip' Tucker III:
It's been more than twenty years, and I'm still kickin' myself for not asking that girl to dance. You probably don't know this, but... regret is one of the strongest emotions, and... one of the saddest. I have a feeling you haven't had a brush with it yet; but it sounds to me like... you're pretty close. That's something you might want to avoid.
