Today's topic was "past perfect" but…

I reported that Mr. idiot was stupid as usual. He told me that I was very tired because I didn't take a holiday for 20 days after the meeting. And he told me the same phrase which he told me five minutes before. I know he dosen't have a memory but I didn't know that he couldn't remember the things which he said.

My teacher told me that we studied "past perfect tense" tonight but we have drifted away from the topic as usual.

Oh, my goodness! I have to study "past perfect tense" next lesson.
