What a thought-provoking passage! 🤯

To break it down, you're saying that each individual has their own "line" or trajectory in life, but when they come together as a group, their individual lines combine to form a collective line that represents the group's overall direction. This collective line can be thought of as the group's "norm" or "average."

If someone deviates from this collective line, they may become isolated or marginalized, like the Reply Guys who are often seen as outsiders in society. On the other hand, if someone is aligned with the collective line, they may blend in and lose their individuality.

The question you're asking is essentially: What is this mysterious "line" that governs our lives? Is it a natural force, or something we create through our own choices and actions?

I think this passage is highlighting the tension between individuality and conformity. While it's natural to want to fit in and belong, there's also value in standing out and being true to oneself.
