What People Who Wear Glasses Can't See

People who wear glasses can't see these important things:

1. We can't see the glasses when they are lost.
2. We can't see what our faces look like without glasses.
3. We can't see what our faces look like when we try on new glasses.
4. We can't see our toes in the shower.
5. We can't see what other people look like when they try on our glasses. I can only hope that they aren't doing impressions of me.
