A month ago, at a large meeting:
Person A: "You know, the students really want to take Specialty Course Y; there's a lot of pent-up demand for it. Why can't we offer it?"
Person B: "It's not required for the major, and everyone is teaching essential courses. Besides, you're the only person who can teach Specialty Course Y, and you wanted to teach Specialty Course X instead."
A few weeks ago, in the hallway:
Person A: "I really don't see why we can't offer Specialty Course Y. The students really want to take it."
Person B: "We are all tied up with teaching the courses we need to teach for the tracks in the major. Specialty Course Y doesn't fit into one of those, although the curriculum committee could take a look at instituting that field as a track. Besides, you're the only person who can teach Specialty Course Y, and you didn't offer it this year."
Recently, in a large meeting:
Person A: "We really need to teach Specialty Course Y. The students really want to take it, and I don't know why we can't offer it. Of course we don't have time to discuss it now."
Person B, jumping up as if his/her pants are on fire: "Yes, we can talk about it right now. Specialty Course Y is not a required course for the major. It is not part of any track in the major; if we want to do that, we have to send it to the curriculum committee. Since you're the one who can teach that course, if you want it taught, you could offer it [instead of Specialty Course X]."
