..When you ask a simple questions and it takes time for him to answer..Bcoz he needs time to pabricate words to say first..ITS PRETTY OBVIOUS that he or she tells lie..And when he or she raised his voice in answering your questions meaning he or she tells lie, to you.. bcoz it made him guilty that made him so upset..OBVIOUS! ..
Bcoz when someone ask us a questions and we have nothing to hide..WE CAN give the asnwer right away..bcoz it directly from your heart and mind..NO NEED TO TAKE TIME TO THINK noh..lol..
