Here is another highlight -- not exactly a good one.
One student who had not really been paying much attention and had actually done some disrupting, looked at the chart that I gave them all in order to prepare for the test. He said to me, "I don't get it. This just looks like a lot of random words." I replied, "I'm not surprised" At which, one of the girls who sits in the front, has been paying close attention, and gets it, laughed.
It made me think, though, that I suppose it is obvious that most people would think of "if", "it", "is", and "in", as just words. In fact, how different they are!
