Learning is a never ending process and whatever the age, we should always keep on learning. Infact life teaches us a lot.

We learn through the books that we should be good to our fellow human beings. But being good sometimes may  put you into many troubles and to overcome those, it may take years.

So a proper estimation must be done on whom to believe and how far the person can be believed and make sure that the particular situation that you are facing with him will not influence your future in   any negative way and only then promise a person.  Finally belief on any person, though however closer is strictly not recommended these days. It will be better if we keep this in mind and act accordingly
