When winter came, I soon stopped wearing my eyeglasses — the ones for seeing distant things clearly — when I went walking. It took a while to make up my mind to do it, since I didn't want to miss any wild animals that might happen by. But when you've got a scarf pulled halfway up your face and your warm breath escapes it, the lenses of your glasses fog up and they do you no good anyway.
On the other hand, if you don't wear them you see strange animals way out in the field. Some of them are walruses.
