Well. I will admit I was a bit ticked. If you're going to be gone for a seminar or something else unavoidable, that's one thing. Or if you ask me, say, a couple days in advance. But springing it on me the day of, just because you haven't finished work that's your own responsibility? And this coming from the same person who had me come up with a lesson idea for a class that would be observed by some middle school students on the spur of the moment on Friday, the one day I don't have a planning period? (Although, honestly, I rather expected that one, so I wasn't completely unprepared.)
However, it was the deadline for turning in grades today, and I know from experience what a crunch time that can be. So I can understand being desperate enough to want just a little extra time to get everything done. Plus I did, in fact, have a planning period available, in which I didn't really have anything much to do except read. So I agreed to handle the class. But I will consider it to be a special exception.
I did have one student come up to me after school to say that she's worried about how she'll get along with her homestay family on the Australia trip. I don't know what she thought I could do about it, but maybe just telling someone made her feel better. About the only advice I could give her was to be sure to tell the host family right away if there's any food she can't eat.
