Mysterious

I was a bit confused about this lot, but a very nice nurse explained. The "Recovery" box is pushing some pain relief into me via the tasteful tube on my shoulder. The box on the floor is monitoring the slight air leak from my lung. The doc offered to take a photo of my wound - but it's not suitable for blipfoto.
I woke up in the middle of the night and was a bit confused as to where I was. Then a man just wearing a pair of underpants walked by. He kept saying "I have to get this out" as he trailed a urine bag across the floor. He stopped for a chat, but I suggested he go back to bed.
