This is a place to share greentexts and witness the confounding life of Anon. If you're new to the Greentext community, think of it as a sort of zoo with Anon as the main attraction.

Be warned:

Anon is often crazy.
Anon is often depressed.
Anon frequently shares thoughts that are immature, offensive, or incomprehensible.

If you find yourself getting angry (or god forbid, agreeing) with something Anon has said, you might be doing it wrong.

This is dumb as shit. Hot air balloons only go so high, less than 70k feet according to records. They only stay aloft if the heat is continually applied, if not, air cools and they sink. They move with the air, and the air moves with the planet.

This doesn’t work for the same reason jumping in an airplane doesn’t slam you into the back wall.

70k ft: 21,336m
