11. I believe a person can't be cheated completely provided he trusts/considers his instincts. You all must've come across a similar situation as described here:
            We meet so many people in our daily lives. But at times you come across someone who doesn't carry a very decent view in other's opinion & so you are cautioned about him/her. But, when you meet that person, though you are cautious, you feel that you have developed a certain 'unexplained' liking for him/her. And you look forward to meeting that person . And , likewise, when you meet someone with a very good reputation, though you are a bit free with him/her at first, you start feeling a certain kind of 'unexplained' uneasiness/fear.
             I beleive that these 'unexplained' feelings are generated by our instincts/intution. So, you can be sure that, however good an actor a person is, he/she can't fool you completely.

      12. We all are taught about good & bad conduct/character, helping/loving nature, etc... or in short, how to be a good human. So, as we grow through the years & different circumstances, meeting different people & their views, we gradually develop our own notions of what is good or bad .
          So, consciously/subconsciously, our curiousity (to test our own nature & get a positive confirmation that we are good/better then the rest) also grows. And we set ourselves a challenge to prove that we are really going to be a good, caring, loving, supportive & trustworthy person ; so that we can feel proud/good about self. So, we start searching for someone whom we can be free with (to exhibit our true nature) & also who's considerate enough, not to hurt us if things go wrong. And when we find such a person, we fall in love & our test starts.
      
13. Well, as every thing has got limits; so does friendship. An honest friend should limit himself/herself to helping his/her friend only when he/she feels that his/her friend is doing something which is justified .
                        Just because the other person is a friend doesn't mean that you are not supposed to advice/suggest him/her on your views regarding right or wrong.
If you feel that your friend is doing something wrong, then you must try to stop him/her by letting him/her know your views. But do remember one thing, you can only try (there ends your limit) ; the decision to take your views or not, will be solely that of your friend . If you try to be forceful, then he/she may feel that he/she has lost you also as a friend & may not confide in you in the future. Thus, he/she may lose a valuable asset from his life & may realise it only after it's too late.
