On Meeting An Old Friend

Two old friends-- the solar system and humanity-- have a heart-to-heart exploring their differences at a bus stop in the Universe.

"Just because we don't talk doesn't mean I don't think about you."

1. What recursive structure is, and how humanity follows it
2. A brief overview of how we go from atoms to the human body
3. Planet groupings, why planets are spherical, and why planets orbit the sun
4. The meaning behind the biology lesson of "structure determines function"

...all through the awkward, tense conversation between people who used to know eachother.
