Remember when you were young and you had an assigned seat in school? Made it easy for everyone. No one had to actually discuss the process of seating arrangements and potential conflict could be handily avoided.
As an adult we similarly have assigned places. Without full awareness we gravitate toward widely accepted and expected modes of behavior given our educational attainment, inherited socioeconomic background, technical ability, etc. However, the resistance is felt if we cross these invisible boundaries.
From what I’ve experienced, the people who get the most out of life are those that notice these boundaries and slyly bend and contort them to their will.
