I don't, but there are times I've wished I had. It isn't because I see it as "desecrating" a book - I'll dog-ear, I'll break a spine, I think books should be loved however the owner wants to love them - I myself tend to think of loving a book like loving
The Velveteen Rabbit - the more beat up it is, the more it's been read and enjoyed and loved. I just don't think about highlighting or underlining when I'm reading - I'm too busy reading and (hopefully) enjoying. There are sentences or passages or conversations that I read and think "Oh that was lovely" or "I wish I had that talent" - and I'll read them several times before I move on.
There was a book I read a while back that so beautifully & perfectly described my feelings about the beach and the ocean, and when my mom and I talked about the book later she knew the exact passage I was talking about. I later found a used copy of the book (I'd probably read a library copy) and bought it so I could find the passage. I'm not sure I found the exact one - that's a prime example of wishing I'd somehow made note of that passage. I'll probably read the whole danged book one of these days just to find that one passage! Or at least read up to that point - and I doubt I'd be able to stop there...but this time I
will get up and find a highlighter!
