I can never remember this: When painting a ceiling, do you roll it out
parallel or perpendicular to the main natural light source? The 3 windows
in the room I'm painting all face east.

a) you wouldn't roll solely in one direction anyway, you'd roll in a couple
directions and at angles to any straight lines in the room
b) with flat paint and careful application, it won't matter anyway.
