Expecting is one of the nature in human beings.but most of the times,it results in being unhappy.
many days ego,one spiritual guru once said that expecting is not bad but we should not be hurt if it was not met.
it seems difficult to not be affected.To be in safe zone means not to expect but it's too impossible like situation.we have to talk with ourselves in every such situation.the reality is that when we expect something,we lose our independence in being happy.
