I felt pretty bad because I didn't anticipate it at all, nor did I know what they were doing and what they weren't doing, so my own class was completely improvised. I have to say self-critically that it had no structure at all, we were just analyzing the sentences on the board. (I summoned the students and dealt with the sentences one by one.) I didn't feel completely bad about the lesson, but I wasn't particularly good either.
