You must have heard the following line a lot of time.
Use your common sense!
Well, just what does the common sense mean? To me, common sense is broad and one’s common sense doesn’t always make sense to another. A lot of things could have been deemed to be common sense to me when it comes to computer but I can’t really expect it to be common sense to my parents, can I? It’s nothing really, but I just dislike people referring something to common sense. I might have done it before but definitely subconsciously. Something that I would refer to as common sense would be like an airplane can fly.
More often than not, I heard of people shouted out the above line without thinking whether or not it is really about common sense. If it were me who were the receiving end, I would definitely say that it is YOUR common sense, not MINE!
