Fever

K has been running a bit of a fever for a few days now.  Last night was the worst it's been for sure.  He woke me up at around 3 am to talk me through a particularly unintelligible math problem that was plaguing his fevered brain.  Something about 1 through 5 of 10 and then 1 through 6 of 10 is what I remember prompting me to ask if he was thinking of permutations in his sleep.  I then forced more ibuprofen down his throat and convinced him to go back to sleep.  He was understandably annoyed that I wasn't entertaining his mathematical prowess.  Clearly I don't know genius when I hear it mumbling incoherently in the middle of the night.
