fearful symmetry...
"When you fall in love...I guess nobody ever does mean to fall in love. But it happens, and love brands itself on your brain. It's like a new street appearing overnight in the city you've lived in your whole life. The street is one way -- you can't turn around and get off it -- and it curves up ahead so that you can only see far enough to know that you are veering into the unknown." - Fearful Symmetry
