Twin Peaks [Season 1, Episode 3]

There is a sadness in this world, for we are ignorant of many things. Yes, we are ignorant of many beautiful things — things like the truth. So sadness, in our ignorance, is very real. The tears are real. What is this thing called a tear? There are even tiny ducts — tear ducts — to produce these tears should the sadness occur. Then the day when the sadness comes — then we ask: "Will this sadness which makes me cry — will this sadness that makes me cry my heart out — will it ever end?" The answer, of course, is yes. One day the sadness will end.
