Little House on the Prairie

P demonstrated his reading comprehension skills this evening as I read a chapter of Little House on the Prairie, which he had been pre-reading for several days. About seven pages into the chapter I came across the phrase 'fever n augue'. Having never heard it before and unsure of how to pronounce it, I trimmed the statement down to 'fever'. Parker immediately corrected me, despite my sitting several feet away and him not being able to see the page from where he was sitting.
