This question reminds me of one action which means opposite between two different cultures. The action of nodding the head up and down means "yes" for Filipinos but means "no" to Japanese culture.
This only shows that perceptions differ, not only in the personal level but in the whole lot of the complexities of human existence. This is perhaps the reason why Matthew 7:1-5 expounds on "Judge not that ye be not judged. For whatever mete you measure to someone will be measured back to you."
