She came the Callan lesson 2min late but she didn't say sorry and finished the lesson on time. She didn't try to extend the lesson even though I asked her there were still 2min left. In addition, there were too many mistakes she spoke in the Callan lesson. She only game me just single new word. I could not proceed as far as I expected. It doesn't matter if she was not used to teaching, but her attitude was awful as a teacher. She should be punctual at least.
