Every one fears it i think

I am drowning in a pool of your love
The goalkeeper was a mean hornet
America is made of luscious candy hills
Your love is a sweet pie
Thomas Eliot works multiple themes in the poem, however in general, his usage of imagery mainly represents ageing and decay. In the lines "When the evening is spread out against the sky / Like a patient etherized upon a table", the phrases like "sawdust restaurants" and "cheap hotels," the yellow fog, and the afternoon "Asleep...tired... or it malingers", represent decay. The character's concerns about his hair and teeth which is mentioned in the lines "Combing the white hair of the waves blown back / When the wind blows the water white and black," show the problems about aging.
There are many different ways poets can use visuals to affect the poem; these graphic elements include simple things like line length, word position, punctuation, and capitalization
