Okay, I'm sold. I guess I'll go whisper sweet nothings to my sad looking pothos. If it dies anyway, at least it heard some kind words first.

Eh, it's cool I guess. But who really cares that much about old mall floors?

That's the kind of guilt I could live with, honestly. New roof trumps good karma.

Read a study from a museum conservation lab that said skin oils are pure acid and cause permanent damage over time. That old binder gave you terrible advice, maybe as a prank or from outdated training. The weird shade on your project is likely the start of that oil-based decay. Always wear nitrile gloves with acid-free paper, no exceptions. Your hands have salts and grease that paper absorbs like a sponge.

Man, that's why old machines always have their own weird rules.
