A critical time during conversation is when you are shouted or asked by other person and you did not feel like to answer it. Maybe because the question was harsh, or judgemental, or overpower yourself. Whatever that is, you need to be get ahead on those critical time. Be silent for a moment rather than answering it with sugary emotions. It could ruin your relationship, but most important-it will ruin yourself. That person just want to communicate with you. In his or her own way. Maybe he or she really just want to reach you, or basically just care with you. Answer it. Calmly. Or with laugh. Don’t stressed out to much about what the content of the question was. But how you answer them. That’s what matters.
