Keeping silent doesn’t mean that you don’t have anything to say, but it means that talking isn’t necessary for that moment in time. It’s not that you don’t have the right to express yourself when the need comes at that same moment in time.
Answering questions brings promotion, it bring honor, dignity and prospect as well when you do well, but it also brings disrespect, dishonor and shame to your dignity and your personality when you get it wrong. It’s better for you to know it fully or you keep quiet and keep watching in order to keep your respects for yourself and earn your dignity as well.
Don’t talk too much in the public or make unnecessary arguments with people in the public, remember that while you are talking and making argument with people, there are intelligent men and women around the corner watching you making argument, these people will put you to shame when they find out you’re giving false information to the public. They are ready to drag your name to the mud and put you on a precarious position which you may not survive.
Do not argue too much with one who is ignorant because when you do so, he will not understand your point no matter how much you try your best to put him on the right track, he will never get you right. You will waste your energy and saliva in vain.
