Our lives are made up of choices. Big ones, small ones, strung together by the thin air of good intentions; a line of dominoes, ready to fall. Which shirt to wear on a cold winter's morning, what crappy junk food to eat for lunch. It starts out so innocently, you don't even notice: go to this party or that movie, listen to this song, or read that book, and then, somehow, you've chosen your college and career; your boyfriend or wife.
