One day, when looking around at your friends or co-workers, don't focus on their faces, focus on their ears. You'll realise how weird ears actually are.
You'll also begin to notice that when talking to people, or looking at people in general, your attention focuses on the area of the face which doesn't reach the ears.
Thus, when you actually DO focus on the ear, it will seem like a foreign object, something that shouldn't even be there.
OMG I KNOW IT'S AN EAR BUT WHY DOES IT LOOK SO WEIRD.
