Klaxon and Zarf get a lot of nose bleeds. They evidently both suffer from a medical syndrome with the single symptom of your nose spontaneously bleeding. There is no warning, or so I am told. They are NEVER picking their noses, they both attest when I suggest easing off the nasal spelunking. They are pretty good at getting to the bathroom when the nasal blood geysers begin. Usually I don't even bother to check on them till the bleeding has abated and I need to contend with a bathroom that looks like a scene from Carrie.
The other day in the midst of a particularly profuse session, Klaxon (age 7) came into the kitchen. "Look. I stuffed wads of tissue up my nose to keep the blood from dripping on my clothes."
"Good job," I said.
"Yeah. I look like I was in a bar brawl. Just like Kirk."
Proudest moment of my life.
