characterized by peculiar or unexpected traits
It strikes me that I have a couple of quirks. 'Oh, just two, I beg to differ,' say all who know me.
I've had two odd reading experiences in a row. I don't need to mention the titles since the authors are alive.
The first one was a biography. I think perhaps not too much is known about the subject, and often the author would say 'may' or 'probably' about various incidents. For example the person 'may' have seen a particular movie that night. I couldn't stand it. I know that biographers don't know all the facts, but I'd rather the author limit the book to what is known.
The other book was a memoir and it was written in the present tense. Is that the right term? Something like, 'Nan and I are eating our dinner of potatoes and carrots.' I would rather read, 'Nan and I ate a dinner of potatoes and carrots.' Tom told me this is a common way of writing, but I sure don't like it. I don't even like an oral story told to me that way. If it happened in the past, I like to see or hear the past tense.
So there you have two quirks of Nan.
