Do you see a lot of this in what you have read or written yourself? I'm still taking a break from my memoir, but I have looked it over for passages that seem repetitive. This was one of the things I looked for when I first began revising/rewriting it after the initial draft that I had begun two years ago this month. But deleting some of these things just made it shorter and since then I have been adding more to make it longer, what seems like the typical length for a memoir. Some of the details I have added over the time I have been working the story may, in some people's eyes, seem frivolous, but I have seen other people's memoirs deliver such details that might seem just as frivolous to some. Such as fantasizing about going on a game show, watching the summer reruns of Friends, going to see movies I had only some interest in in the summer of 2001 while I was working for a boss I hated. I would do things like those to get my mind off the awful days at work I was having then. In the beginning, I had not said exactly what I had done on my days off from work, just that the two days off always seemed to pass too quickly and that I had little time for myself before it was back to the awful job. Does any of this seem annoying to you? (Though I am paraphrasing).
And I noticed in my diary novel I repeated the phrase "trigger(ed) (ing) my anxiety" more than once. My mom had suggested rewriting that phrase in subsequent lines, though I have yet to even try doing so. Would this seem annoying to you? (Though I know you don't know that context in which it is being used).
As for using similar character names, this seems hard to avoid when writing something from real life. Using a name more than once could cause confusion, but seems weird when you have known more than one person in your life with the same name. I mean, how many Jennifers have you encountered over your life so far? Probably more than you can count or name. I didn't refer to any one specifically by this name or other over used names such as Karen or Lisa, rather in one part I made reference to "one of the many Jennifers, Karens, or Lisas..." and later to "another of the many Jennifers, Karens or Lisas...," implying that the girl who was speaking then had one of these names. I did this partly not to use the real names (which I worked hard to avoid doing), but also to emphasize that fact that I did (and still do) know a plethora of girls with these names. Every other girl to school seemed to have one of these names and that it was hard for me to grow up among them with a not-as-common name.
How do you writers work around this?
