Keret explained his impact on the literature in Israel somewhat like this:
The written word has not changed in Israel in thousands of years. Authors who write in English worry about seeing their book up on a shelf next to Shakespeare. Israel’s authors worry about seeing their book next to the Bible. (Also, as I learned while in Israel, anything with Hebrew writing on it does not get thrown away, rather archived or buried.) Yet, while the written word has carried through, the spoken language has changed. It is common in Israel, when saying something like “see you later,” to say, “Tov yalla bye.” This phrase is a combination of three languages: Hebrew, Arabic, and English. (Tov meaning “good,” yalla meaning “come on” or “hurry up.”) Keret incorporated Hebrew slang into his writing, which was unheard of, and caused quite a reaction in the Israeli community.
This was an incredible story, especially since I recently went to Israel, but mostly because this is so different from writing in English. When studying creative writing I have always been told to get the dialogue as close to what people actually say as possible. A common writing exercise is to go to a public place and just listen to people, recording it all down, because this informs the veracity of the writing.
Not to mention their reading selections were fabulous.
