first-stupid nurse... why couldn't she give you the # now? what difference would it make?!?!
second-of course I am glad I asked! I would definitely fight for your original time. That is what seniority should be about... you getting to choose. And I would choose that schedule too. besides, by 4pm your ankles will be swollen from the pregnancy... you'll do better teaching in the AM. plus, you will have all those u/s appointments to go to
