Once in a lifetime experience

Something happened today that I never thought would ever happen in my life. Let me set up the scene. On Tuesdays I assist a particular class of BTS (20-year-old future papermakers or computer programmers, I forget which field) which has two hours of English per week with Professor Batina. For the first hour of their session, I have half the class. Today, as usual, the bell rang signaling the five minute break after which they would return to their regular class. Here's the stunning part: Not only were they not packing up early, my students opted, nay, REQUESTED, to forgo their smoke break and finish the lesson with me. HUH???? What educator has ever experienced a class of students ASKING to stay past the bell? (OK, probably Jo Anne.) I feel a little sorry for the Professor Batina as I think some of them might get a little testy towards the end of the session without their nicotine fix. Sorry!
