"Today, with the introduction, I'll teach you girls the definitions of Social Psychology. Then we shall discuss them."
We write down 10 of them. We 'discuss' (read: dissect) them till we're S-I-C-K of each and every word.
"So. Today we'll discuss the definitions."
One brave soul dared point out that we'd already done so.
"No, we haven't."
We proceed with the discussion. Which is the same as Lecture 1.
"We'll do the definitions today."
We stare with out mouths open. I'm not kidding.
"Hello, girls. Today we'll cover the definitions and discuss them."
We don't bother pointing out that we've been doing that for more than a week. We discuss the definitions. Again.
Does this woman have a memory disorder or something?
