Inorder traversal Memes

The classic programming classroom standoff! When the prof asks for questions, they're expecting softball queries about office hours or the syllabus. Instead, this brave student drops a data structures nuke about traversing binary trees without recursion. The professor's immediate pivot to "about my personal life..." is the universal signal of "I don't remember how to solve this either but will never admit it." The student's quick backpedal is the silent agreement to maintain the professor's dignity. This is basically the CS equivalent of mutually assured destruction.
