the.com/parallel
Two lines that get along perfectly by never actually meeting.
means Running alongside something else at a constant distance, never converging or crossing — whether lines on a page or situations that mirror each other.
from From Greek parallēlos, built from para- ('beside') and allēlos ('one another') — literally 'beside one another.' The word walked from geometry textbooks into everyday language, picking up its figurative sense (parallel lives, parallel universes) while keeping its original geometric meaning intact.
