Tears as Social Phenomenon
November marks the point in the year when the cold beings to set in. Fields, buildings and streets are blanketed in heavy fog, blurring the city like an old painting. Trees look like skeletons and dawn frost carpets the grass. It is the time when biting winds gnaw on our skin and whip chilly, wintry air into our eyelashes. Our eyes tear up, because it's freezing.
Tears keep our eyes lubricated when it is cold and blustery; wash away smoke, dust or other irritant substances; and protect us from foreign particles that enter the eye’s environment. Though some animals do have the physiological ability to produce tears, humans are the only creatures whose tears can be triggered emotionally.
