Twelve-Year-Old-Son-itis

I am suffering from Twelve-Year-Old-Son-itis. It doesn't make it any easier to bear, but I hear there's a lot of it going around. The symptoms include: frustration, exasperation, exhaustion, more frustration, screaming, incoherence, did I mention frustration, and lack of sleep. Why is it that they can recite sports scores, game summaries, entire lines of dialog from movies, words to every song they have ever heard, funny stories the teacher told...But they cannot remember the book they need for their homework, that they even have homework, that they are supposed to unload the dishwasher, that I asked them to pick something up/put it away/throw it away? Arghh.
