Yesterday he (the student I hid from the other day) popped in ... again. Wanted to know if the test scores were back yet. (They're not, which means I'll get to see him at least one more time before the end of this week.)
In fact, I was so good (and feeling a tad guilty about the other day) yesterday that when he said (as usual), "May I come in?" I had an easier than usual time NOT groaning and saying "If you must". I've never done that yet, but I occasionally am afraid it's only a matter of time.
