You're not in the mood to be crossed for these few days, and you may well find yourself in an argument or debate. If it were just a friendly discussion between two people who have different viewpoints, that would be one thing. In the best of all worlds, you could learn from each other and increase your own perspective.
But what's more likely to happen is that both parties will dig in, feeling righteous and oh-so-virtuous about their ideas, unable to entertain any concepts that fall outside their narrow philosophy. Don't let this happen to you! Rather than engaging in verbal combat or deriding anyone else for their viewpoints, consciously turn off your inner judge. Listen. Walk a mile in the other person's shoes -- without expecting them to walk a mile in yours! The more mental flexibility you develop now, the better you'll be in the long run. This is a great opportunity to learn to be attentive to ideas and concepts that are foreign to you. It doesn't mean you have to embrace them, just entertain them. The mental growth you experience will be well worth the words you bite back.
