This morning I had to have a talk with my class. You know, one of those "you need to shut up when I tell you to and stop being so disruptive" talks. After the class was over, my host teacher came up to me and told me that I was smiling throughout the whole thing. She thinks I've just not got a mean bone in my body, and I'm going to have to work a bit to develop the all important game face (and accompanying teacher look) so that the students won't keep trying to push my buttons. I'm very glad that I have her, a very experienced teacher, to observe me and give me tips.
However, the truth of the matter is that I'm not a super smiley person. If I'm comfortable, then I probably won't be smiling. I just get very smiley when I'm uncomfortable (which is why I tend to smile my head off in the classroom). When dealing with uncomfortable and serious subjects, I get downright bubbly. R actually finds it a little creepy when I'm smiling and giggling while talking about death.
