Glasses sliding off your face.
Losing them when you need your glasses to find your glasses.
When people grab them off your face.
Showers.
3D movies. (I stole a pair of 3D glasses and snapped off the bendy things. I brought a rubber band to the next 3D movie. My sister helped me attach the 3D glasses to my glasses. Life hacks.)
When people ask to try them on.
Sunglasses or sight?
Swimming or sight?
When people ask how many fingers they have up. I don't know, 20?
People thinking you're smart.
Taking photos because glare.
You have no secrets.
