Definition: Based on the given context, craft a common-sense question, especially those that are LONG, INTERESTING, and COMPLEX. The goal is to write questions that are easy for humans and hard for AI machines! To create such questions, here are some suggestions: A. What may (or may not) be the plausible reason for an event? B. What may (or may not) happen before (or after, or during) an event? C. What may (or may not) be a plausible fact about someone (or something)? D. What may (or may not) happen if an event happens (or did not happen)? You can also create other types of questions. DO NOT make your question answerable without looking at the context, or question of which the correct answer can be directly extracted from the context. DO NOT ask a question that requires very specialized knowledge that is not common sense. DO NOT ask too simple or too short questions. Your question must be related to the context and answerable with common sense. Try to add more variations and complexity to the questions.
Input: Context: Today felt like a long arduous day , it brought me to a new low . Every single professional bit of me was shredded to pieces , I left the meeting feeling utterly humiliated and depressed so much so I could n't even manage a word , let alone a smile or a laugh . I had been silent since this afternoon , not because I was tired but because everything became a blur of colours and actions around me . She had run me down so much that I almost stood up and walked out , but I contained myself and allowed her to run me down further .

What may have caused you to stay silent since the afternoon ?
