What better photo to represent the letter X, one of the definitions of which is 3: an unknown quantity. Also, 1: the 24th letter of the English alphabet and 2: the roman numeral 10. I have no idea what this photo is of. Actually it looks a little scary to me. So it is a totally unknown subject to match the definition of an unknown quantity.
Hate the unknown. Just want some predictability and stability in my life. Life is an open book, life is an adventure, throw caution to the wind. I hear these phrases and think they might be good for those people needing a little excitement in their lives. But I've had enough in mine. Opening that door into the unknown has ceased to entice me. I'm not sure I want to find out anymore.
