Yunior and Holden

In Drown, there were parts of the story I came across that were abrupt and disturbing. Usually troubling events whether fictional or in real life, creep up on you. Foreshadowing a negative situation typically includes an eerie feeling or dark descriptive words to decribe the setting. In the story of Yunior and the bus driver, the setting really gave me no indication of that molestation situation happening. It was almost as if it was meant to be mentioned, then "swept under the rug". Yunior's story reminded me of Holden Caulifield's character in the Catcher in the Rye.  Instances of exual molestation were mentioned in the Catcher in the Rye but after it was mentioned, it was no longer discussed in the book. Sexual molestations are uncomfortable to even think about, let alone write about. I often wonder if these mentionings are a way for the authors to divulge pieces of their lives in books without really using themselves.

Do you think that by using fictional stories, writers are masking troubling events that they have been apart of or witnessed in their own lives?
