I think I'm running a temperature.
Julie suggests to her husband, David, that he should not go to work because he isn't feeling well.
David : I think I'm running a temperature. My head is spinning, my mouth feels cotton, and i have a scratchy throat.
Julie : Let me see. Hmm, you'd better stay at home today. And don't work on the computer, staying up late with that thing has obviously played havoc with your health.
