Indeed, in retrospect, my personal issues, no matter how stringent they might have been, should not have stayed in the way of exercising my common sense in the relationship with the rest of the individuals. From this perspective, it is most likely that I should have followed what the son of the writer Harriet Beecher Stowe, C.E. Stowe said in relation to common sense, that "common sense is the knack of seeing things as they are, and doing things as they ought to be done." (ThinkExist.com Quotations, 2006) Therefore, I now come to realize that it is of little importance the actual personal problems we are faced everyday because the people around us, and especially our friends, have no blame in them and acting foolishly towards them would not improve or create a result to our own issues. On the contrary even, when we tend to act without using our common sense, that is our basic moral rules of behavior, me may end up losing our friends.

Taking all this into consideration,...

Common sense is a rare but natural quality of each human being, a quality we must constantly improve and never forget to use. It may earn the respect of our friend, while its misuse can make us lose them. From the perspective of my personal situation, I hope that, despite my lack of common sense at one point, my friend can, in his turn, see the personal circumstances and my apologies.
