I can assert, with some level of shivering, that on a cold evening with completely wet dirt roads, each and every muddy puddle is concealed by the sleet accumulating in your glasses. I do harbor some doubts since I have a nagging suspicion that towards the end, I missed stepping into one 🙂 Aargh!! My carefully cultivated sartorial sense was unceremoniously compromised as I trudged back home in my blue running jacket and what to any eyes with unsleeted glasses would appear as dirty brown shoes.
