The English translation was given as "Mary and Shoko are talking about their friend Tom."
The following two sentences I guess would mean the same.
So how does the feeling differ between (A) and (B)? Do people say (B)? Do people say (C)? How does the feeling differ between (B) and (C)? Would anything change if they were talking about say a test rather than their friend Tom?
