Are you a spine breaker? Or a dog-earer? Do you expect to keep your books in pristine condition even after you have read them? Does watching other readers bend the cover all the way round make you flinch or squeal in pain? [Suggested by Mariel]
It makes me sad when people bend the covers, break the spines, and dog-ear pages. I mean, some general wear and tear is to be expected, but you don’t need to abuse the book. Everyone likes to read books that look pretty and are nice to hold, not feel like you’re holding something that lives on the street.
Am I being too bitchy about this? Pristine isn’t necessary, but neither is destroyed. I like to keep my books in a decent condition — I use bookmarks, only open them as far as is comfortable to read, and I try not to throw them about (although I toss them in my purse on occassion).
