Clarification

Okay - so some of you have contacted me asking me to provide further explanation of what my lecturer meant.

He had had some students in his office because they had failed all their exams. But he wasn't going to have me in his office because I failed all my exams. Why? Because I didn't fail all my exams.

Think of it like this - I thought that what he said was equivalent to "Because PTR has failed all his exams we won't have him in our offices". Whereas he thought that what he said was equivalent to "Because PTR has not failed all his exams we will not have him in our offices like all the people who are in our offices because they failed their exams."

Here's another way to think of it: linky

Let us never speak of this again.
