The following exchange is a relatively frequent occurrence in our household:
Sra (leaning in to Ian): Do I have a fever?I'm not a hypochondriac in the least (although Ian might disagree), but I am a very temperature-sensitive person. I get cold at 70 degrees, and I keep a blanket in my office which I wear around like a cape during the winter months and over-air-conditioned summer days. You would think my plentiful layers of fat would keep me warm, but I think deep down I'm actually a cold-blooded creature who needs to bake on a sunny rock in order to keep warm.
Ian (feeling forehead): No, you don't have a fever.
Sra (leaning back, pensively): I think I have a fever.
Ian: You don't have a fever.
Sra: Are you sure? Feel again.
Ian: Your forehead is actually quite cool.
Sra: I definitely have a fever.
So the thing is, I can detect even the slightest change in my body's temperature.
And I have a fever, goddamnit!
