Monday Morning, & I Have Found A Film of Particulates

On the morning of Monday, something really spectacular occured. I went to take out my glasses, which were put away for several days. Upon retrieving them, I noticed a film! Yes, that's right, a film, on them. It was just like the film from a roll, the coating, that is. I was perplexed. I had not done this. It was evenly coated on the lenses, and luckily I was able to wipe it off using some cotton. What caused it? Well, that's something that I will never be able to explain, at least for a while...
