My local library had a first edition with whole paragraphs faded from skin oils. Seeing the actual damage changes your mind fast. I wish more places had a UV light to show people. It makes the problem real instead of just a rule.

Totally, @thomas.parker is right about soft stuff. I threw a thick blanket over my desk and it killed a weird ring I had. The room just sounds less hollow now.

Oh man that's the worst kind of modern travel nightmare. You just know the host is sound asleep while you're standing there like a chump. Honestly the universe was just testing you, next time you'll probably pack a power bank the size of a brick.
