how to sustain a friendship does not really mean u cant complain to ur friend of wats wrong. u fighting wit ur friend dosent mean ur friendship is over but it is just a signal some one went wrong somewhere. wen u fight wit ur friend u mostly say am not talking to u again. but is dat wat u should really say? wat u should really say is am sorry but if ur friend dosent listen den shes calling for a cut of relationship. even wen d relationship ends u shouldn't still keep it in ur mind as one big problem
