you ask, why are pizzas round.
so that you think less and eat more. thinking at the table is a gross sin.
the circular confection of pizzas protect us from greed because circles can be cut into an infinite number of equally sized pizza pieces. hence you take without lusting and eat without sinning.
circles are both conclusive and confusing.
then ask again, do blind people have sexual preferences like do they even know lust and jealousy and adultery because these are the sins belonging to our eyes.
we see lampshades and believe they are ufo-s. not octopus eyes or floating planets or translucent jellyfishes but spaceships manned by dust allergic astronauts. however badly they manoeuvre them, these spaceships will not surface as debris in the sea.
