When I think about how these fortune cookies apply to me, I don't really think about how weird or creepy it is that they do - I think more about the fact that these fortunes apply to so many people on a broad scale. It's interesting that people will really resonate with a "new adventure" coming in the weekend, or be thinking about their loved ones enough to really agree with the "absence" adage.
Silly enough is a fortune cookie I got before I started going for Chinese for lunch so often:
"A good way to keep healthy is to eat more Chinese food."
Cause, or effect?
