I'm feeling pretty ill this evening, and the way this sickness has been building, I won't be coming to class on Tuesday. I suppose it's possible that I'll wake up well and re-energized, so it might not hurt to check this page first thing Tuesday morning. But unless you hear otherwise from me, Tuesday's class is canceled. One thing I've learned this semester is not to come to work when I'm too sick to do my job.
In short, my sickness is your respite. We'll simply do Tuesday's class on Thursday. I hope to see you then.
