I was feeding sheets of paper into a paper shredder and stopped suddenly when I felt a piece that seemed to be damp. The other sheets of paper in the same pile were dry, so how is it that this one sheet appeared to have picked up moisture? As far as I could see, this “damp” sheet came from the same place as the others, which was a stack of various documents, flyers from the post and envelopes with their plastic windows torn out. Curious is it not, to have just the one damp sheet in a pile, how can this be?
