You don't believe a word of it, but you're not going to say anything. Stony glares and cold silence will have to suffice to communicate your displeasure, and they will, quite effectively. Others are actually afraid to engage you in conversation this week, and truth be told, you don't much feel like talking anyway.
So you'll keep your opinion to yourself, and in fact, you'll keep yourself to yourself while you're at it. Now, this energy is short-lived and comes only once a year so don't think that your mood will be darkened forever. By next week you'll be feeling like yourself again, but in the meantime, there are some effective ways to deal with this quiet energy. It's actually a fine time for a serious conversation, especially if you can loosen up just a little bit. You're able to say things honestly and directly, which can go a long way toward clearing the air if you've been having difficulty. You can listen effectively if you set your mind to it, and express yourself clearly.
