We cannot judge others before knowing where they come from

Different cultures from different societies somehow tend to separate individuals from one another. In my opinion, we cannot judge others before knowing where they come from, because something that may be considered rude in one particular culture may not necessarily be disrespectful in another culture. For instance, in Tibetan tradition, making noise while eating noodles is used to express that the noodles are delicious, however, in some western cultures this may be considered rude. Thus, judging others from our own perspective is not only unwise, but may also cause misunderstandings and wrong interpretations.
