My body: "lol. Nope. I have a better idea: you're going to sleep until nearly 2pm, then wake up groggy and fuzzy-brained when the phone rings and you're forced to get out of bed. No, I don't care that you napped last night, you're still going to get 14 hours of sleep tonight, dammit."
I'm choosing to think positively about this by assuming that I have just saved myself a week of illness by letting my body have the rest it clearly needed to fight off something.
