Booking Through Thursday: Flapper? Or Not a Flapper?

Over at Booking Through Thursday, here’s this week’s question:

Do you read the inside flaps that describe a book before or while reading it?

I used to love reading the inside flaps of hardcovers and the back covers of paperbacks.
Then I became a librarian. A public librarian.
And now I read reviews.
I find that I tend to avoid reading the flaps, because sometimes enough time has passed between having read the review and actually reading the book, that I have forgotten why I requested the book in the first place–and this is thrilling–like a surprise. (Sometimes I continue to wonder why I requested the book; these are the great unfinished ones that get hauled back in after 5 pages or so of failing to draw me in.)
These days, it’s only in my rare browsing moments that I actually read the flaps — and even then, I kind of squint at them so I don’t find out too much.
Also, since I write about books here and at work, I want to remain untainted by the descriptions of others. I like to discover the story on my own, and I like to describe it on my own.
