When T.S. Eliot wrote the opening to The Waste Land, his primary intention was to capture the disillusionment of the post-World War I generation. For seasonal-allergy sufferers, however, a line such as "April is the cruellest month." must take on a dual meaning. Indeed, sometimes the most annoying symptoms are also the most harrowing, so for those 40 million Americans who bear runny noses and watery eyes through the spring and into the summer, there might as well be a war going on in the cellular trenches of their bodies.
