Humans are amazing creatures — we’re very good at seeing patterns. We see patterns even if the pattern really isn’t there.
Sure, some of it is very high school… but the fact that all of this is so ingrained in us it’s kind of funny.
Of course, not all of this is as juvenile as this. People regularly see Jesus or Mary in the strangest things, from toast or apples.
We are drawn to make order from randomness — if even only in our thoughts.
