My nine year old has a virus called 5th disease, it’s also called slap cheek because it makes his cheeks beat red. It harmless and will pass in just a few days, which makes the timeliness of his joke all that much more impressive.
Adding to the unique set of circumstances, he and his brother just started showing an interest in padded sword combat.
They were out fighting and the older boy hit him quite hard across one side of his face . When I’d heard about it later in the day, and asked him if he was alright he said, “yeah, I’m fine. It just looks like I have 6th disease on one side.”
