Revenge is never a straight line.
Straight lines vary only in length, and therefore are least ornamental.
The song of the curved line is called happiness.
There is no motion in a straight line. A straight line infinitely projected becomes a circle.
I can't draw a straight line to save my life. I just can't draw.
The straight line is ungodly.
God draweth straight lines but we call them crooked.
There is no straight line to a dream.
The straight line belongs to Man. The curved line belongs to God
Draw a straight line and follow it.
