Sideways

Everything about her seemed sideways. That was the only way to describe Fiona. The smile she always wore looped diagonally across her kind face. Even her feline walk leaned imperceptibly to the right as she ambled from shop window to shop window, never in a hurry to get anywhere. She rarely looked anyone straight in the eyes, but when she did, no one could escape the allure of those languid brown pools.
