We were being discharged. When I got the wheelchair into the hallway, I wiped my nose, and there was brown blood. I wiped it a bunch more, and still the blood. Fortunately it was not bright red. Not wanting to trigger a procedural response from the nursing staff, I decided to conceal the blood from my dear wife.
I think that maybe they were a bit rough during the procedure, or my attempts to get air were, and that caused a little bleeding.
During the operation, I got to see the inside of my stomach on the monitor. But I was tired of interesting experiments on my own body. I wanted to go home. So I threw the tissues in the trash and followed my miraculous wife to the elevator.
