That would be me. Gah. I insulted someone without realizing, and now that I realize it, I don't quite know how to bring it up to apologize. I think I need to straight up apologize.
And then I had a student come in to office hours who smells strongly of tobacco. I didn't say anything (because despite tenure, I retain vestigal social skills).
Then in class, the lit mentioned something about cigarettes in a rather negative way.
And I couldn't help wondering if the tobacco student felt pointed out in a negative way.
I didn't choose the lit with that in mind (the cigarette thing is one line among many, noticable), and I don't tend to think about how tobacco users smell when I'm writing up a syllabus. And maybe other people don't notice tobacco smell as much as I do. (And then, of course, more than one student in the class smokes. I just noticed the one because of sharing a small space.)
(I really wish students wouldn't smoke, not only for their health, but mostly, utterly selfishly, because talking up close to a smoker tends to make me nauseated.)
