A carpenter is installing a cabinet next to a wall that is 3/4″ out of plumb. If he follows the lay of the land, then his work will be whack. If he makes it perfectly plumb and level then he gives into his ego. The sin of … something or other.
Split the difference. Install the cabinet 3/8″ out of plumb. The difference is less noticeable and the universe continues to be ever so slightly off balance.
When at the market, and the aisles are full of other shoppers, we tend to turn our body slightly sideways unconsciously, to make room for each other.
