I'm completely drawn to the symbiology of Shauna's earring. I understand Masons revere circles as a symbol of the compass, which I used in the fifth grade to draw circles in geometry. And the square is symbolic of a square that you can use to make squares and measure square things. Historically, and in many cultures, the circle represents our spiritual selves and the square represents our physical selves. The common image of a circle inside a square can be symbolic of our spiritual selves suppressed by our physical bodies. But Shauna's earring is a square inside a circle, and seems to be indicating now that she's clean and sober, her spiritual self has overcome the addictions and weakness of her flesh. Not like that !@#$% Ashlee!
