In any case, I have always realized that the various nonsense had nothing to do with me, although I am sure I provided a nice occasion for their being realized. Students and staff have their own lives, their own nonsense, and it just happens to rain on your parade. Whatever I do, they will take it as being about them, rather than generic. Whatever they do, I must take it as being about them--I just happen to be in the way of their one-car accident.
Also, I have discovered that what I called "brick wall plagiarism" is quite prevalent. Again, what I encounter is generic.
