As I watched these two men chat about a few syllabus weeks, and as the one on the left comes upon one week, he recalls that his teacher says that after they look over the modules, they'll come to class next week to talk about abandonment. I think that abandonment strikes the two as humorous because abandonment is an uncomfortable topic, but in a way that is not offensive to either of the two of them, qualifying as a benign violation. It also reflects on the truth and pain theory, though I do not know the background of these men, so I cannot say how strongly they relate to the sentiment of being abandoned.
