Do you annotate your books?

[SolemnlyDoc]

For those who purchase physical copies, do you annotate them?

I highlight, underline, and write in the margins of my books. It's part of how I read and re-read them, usually I only mark them on my second run through.

What about you?

Man, I do that to mine... can't control myself. But I find it awful tbh, especially if you intend to circulate your stuff.
