From the space station you can’t see borders, schools or group chats. Just one planet trying its best.

The lines that organize your life have real effects and no physical existence. Which school, which side of town, which group is not speaking to which: all of it is agreement rather than geography, and none of it survives a change of altitude. Knowing that does not dissolve the lines you have to live inside. It does make them easier to cross, because you stop treating them as features of the world.

Cross one this week. Talk properly to someone from the other table, the other team, the other group. Most lines turn out to be maintained by nothing more than nobody going first.
