This story is set in a Third Avenue at a summer night and told from omnicient's point of view.
This story describe the confrict of she vs herself.
The climax is that the man hit a telephone pole.
The irony is that though she thought she was lonely and no one would pay attention to her, the man hit a telephone pole because he looked back at her while he kept running.
I think the bridge represent death and the smell of flower represents pleasure.
What the author wants to say (the symbol) is taht "Hold your head up and look around yourself."
