W: How about your exam?
M: I failed again.
W: Why? Did you oversleep again?
M: No, I didn’t. It’s something like this. This time, I made full preparations, but Smith told me he could get perfect marks. I decided to copy his paper and I did copy, though not completely. It turns out that his marks were lower than mine. And we both failed.
W: It serves you right.
