When I was teaching at Georgetown in 1993, I had my office on the same row with her. She would come punctually at the same time around 5:00PM, pass by office, and pear in, and give me dirty looks before walking away. We also noticed that she would use The Arab Mind in her classes on national security. I was also amused once in the library to find a copy of Ghassan Tueni's book, Une guerre pour les autres, with a heart-felt personal dedication by the pen of Tueni. She must have treasured the book before donating it to the campus library. It looked unopened before my inspection.
