Left to their own devices people cluster, people congest.
Congestion, an absence of flow. Sounds like indigestion, constipation. Just as comfortable I reckon.
Gravity, it takes prisoners.
You have to step outside of it to see it. Some people do see it.
Look for these bright stars, and follow them. They’ll give you the velocity to escape.
It just takes a person to keep the flow moving, someone who sees the congestion.
