Read the following context and answer the question.
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 .
Question: What may have caused you to stay silent since the afternoon ?
Answer:


I was in a bad mood .
